Tropical Unrest.

A few weeks ago we were basking in relative calm.   Even those systems would steer away into the Central Atlantic.  Those in the area of the Yucatan Peninsula and into Mexico.   But something was afoot,   I sensed a problem when the system slowed and gathered moisture and dumped tons of rain.

This was the perfect storm.   Harvey began to ramp up.  I referenced this slowing and the dangers, in so many words.   I did not expect what happened.   It was NOT climate change.   It was an anomaly and weather is about changes.  It’s highs and lows, tightening  pressure gradients and a myriad of other things.

As a consequence of what had happened, thousands were displaced and hungry,  exposed and afraid.  Let’s not criticise people who are doing the best they can.

Going forward,  there are new challenges and new storm systems.  This evening here in North Carolina, we are experiencing lower  clouds before the rain.    There is a quasi-stationary front (warm sector) which will keep the temperatures rather uniform, with overnight lows 68-70.

Area Forecast Discussion
National Weather Service Birmingham AL
317 PM CDT Thu Aug 31 2017

.SHORT TERM...

The post-tropical center of Harvey is now analyzed south of Tunica,
MS. A synoptic scale warm front was located via surface pressure
field analysis from the surface low center east to just south of
Tupelo, MS. Across the state of Mississippi, surface winds generally
shift across this front but as this feature extends into Alabama, it
is primarily defined by a pressure trough with little in the way of
a wind shift or change in the thermodynamic environment.

Sounding data along with upper air guidance suggests drier air aloft
is present in greater magnitude to the east and the north while
profiles are more moist to the south and the west.

Rotating storms remain likely across our south-central, southwest
and western counties with a limited tornado risk. While
conditions had become somewhat calmer in the short- term,
additional development across our south and west counties continue
to be monitored closely. Tornadoes remain possible as we remain
in the synoptically favored right front quadrant of a former
tropical cyclone.

Breaks in cloud cover continue across our eastern, southeast and
south-central counties and solar insolation continues to result in
surface heating that is increasing instability values. Wind shear is
most prominent off the surface at this time, supporting broad storm
rotation. Wind shear values will increase across our western and
northwest counties for the remainder of this afternoon and evening
as the remnants of Harvey move into western Tennessee.

Radar imagery indicates storms that we are closely watching in
Pickens, Perry and Marengo Counties with more activity to the
southwest. Our southwest and west-central counties continue to have
the greatest potential for rotating storms and possible tornadoes.

JH/05

.LONG TERM...

Rain chances will drop significantly for Friday as much drier air
aloft moves into the region around the southern periphery of
Harvey`s remnant low. The weekend looks dry for most if not all
of our forecast area with the arrival of northwesterly flow. The
next chance of rain may not come until Tuesday as southerly flow
develops in advance of an approaching upper-level trough.

&&

.AVIATION...
18Z TAF Discussion.

Band one has exited the TAF window to the east and now watching
band 2 begin to work in from the west. Looks to move into TCL at
or just past 18Z and then work into EET and BHM by 20 to 21Z and
then sliding northeastward after that. There should be a line that
moves through MGM and TOI as well, but they may not see the amount
of activity as the northern sites. As the center of the remnants
of Harvey moves northeast, we will see low clouds and showers
overnight at the northern sites along with the main low itself.

Note: Have put in AMD NOT SKED for KASN TAF since winds are
missing from the observation and will be a factor in the forecast
today and tonight.

High rain chances are expected through tonight with tropical
moisture in place. A drying trend will follow for Friday and the
weekend. There are no fire weather concerns at this time.

Mesoscale Discussion 1605
NWS Storm Prediction Center Norman OK
1031 AM CDT Thu Aug 31 2017

Areas affected…Parts of eastern Mississippi into western Alabama

Concerning…Severe potential…Watch possible

Valid 311531Z – 311730Z

Probability of Watch Issuance…60 percent

SUMMARY…Some increase in the risk for generally isolated and
relatively short-lived tornadoes may occur through midday and early
afternoon. It is not yet certain that a watch will be needed, but
trends are being monitored for this possibility.

DISCUSSION…East of the remnant circulation center of Harvey,
tropical boundary layer moisture (mid 70s+ F surface dew points)
remains present in a narrow corridor roughly centered near the
Mississippi/Alabama state border area. Breaks in cloud cover across
this region have allowed for some insolation and destabilization, as
a broken band of convection pivots across the region. Coinciding
with a broad belt of 30-50 kt southerly 850 mb flow, which is
contributing to sizable low-level hodographs where near surface flow
remains southeasterly (mainly ahead of the broken band of
convection), at least some risk for brief tornadoes remains evident.
However, the extent of this threat remains unclear, and will
probably hinge on whether rain cooled air now present across much of
central and southern Alabama can modify appreciably. Currently this
seems unlikely, but a couple of corridors of substantive further
boundary layer destabilization seem at least possible. One of these
may extend north and east of Biloxi MS into southwestern Alabama
(near/north of Mobile). The other may develop near Tuscaloosa
northwestward into areas near/east of Tupelo and Columbus MS.

office for additional information on this life-threatening
situation.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 PM CDT (0300 UTC), the center of Tropical Depression Harvey
was located near latitude 31.7 North, longitude 92.3 West. The
depression is moving toward the north-northeast near 9 mph (15 km/h)
and this motion is expected to continue tonight. A turn toward the
northeast is expected Thursday or Thursday night. On the forecast
track, the center of Harvey should move through central Louisiana
tonight, then move through northeastern Louisiana and northwestern
Mississippi Thursday and Thursday night, and over the Tennessee
Valley region on Friday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Gradual weakening is expected over the next 48 hours.

The estimated minimum central pressure is 998 mb (29.47 inches).

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce additional rainfall
accumulations of 4 to 8 inches from southwestern Louisiana and the
adjacent border of eastern Texas northeastward into western
Tennessee and Kentucky through Friday with isolated amounts up to 12
inches. The threat of heavy rains has ended in the Houston/
Galveston area. However catastrophic and life-threatening flooding
will continue in and around Houston, Beaumont/Port Arthur,
and eastward into southwest Louisiana for the rest of the week. The
expected heavy rains spreading northeastward from Louisiana into
western Kentucky may also lead to flash flooding and increased river
and small stream flooding. DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED
AREA IF YOU ARE IN A SAFE PLACE. DO NOT DRIVE INTO FLOODED
ROADWAYS. Please see warnings and products issued by your local
National Weather Service office for additional information on this
life-threatening situation.

Elsewhere, the outer bands of Harvey are expected to produce
additional rainfall amounts of 3 to 6 inches over portions of the
central and eastern Gulf States and 2 to 4 inches farther north into
parts of the Tennessee Valley, Ohio Valley and southern Mid Atlantic
through Saturday. These rains may lead to flooding concerns across
these areas.

A list of preliminary rainfall observations compiled by the NOAA
Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

STORM SURGE: Water levels along the northwestern and northern
Gulf coast should subside very slowly over the next day or two.

Tropical Depression Harvey Discussion Number 43
NWS National Hurricane Center Miami FL AL092017
1000 PM CDT Wed Aug 30 2017

Harvey has continued to weaken since this afternoon as the center
has moved farther inland over Louisiana. Surface observations
indicate that winds along the northern Gulf coast have decreased,
and the system became a tropical depression in the 0000 UTC
intermediate advisory. Harvey should continue to gradually weaken
as the circulation moves farther inland, and the cyclone is expected
to dissipate over the Ohio Valley within 72 hours.

Harvey is moving north-northeastward at about 8 kt. The cyclone
should turn northeastward around the northwestern portion of a
mid-level ridge that extends westward from the western Atlantic
across the eastern Gulf of Mexico. This steering pattern is
forecast to take Harvey across the Lower Mississippi and Tennessee
Valleys during the next couple of days.

It should be noted that despite Harvey’s weakening, heavy rainfall
and flooding are forecast to occur along the path of Harvey during
the next few days, but its faster forward speed should keep
subsequent rainfall amounts well below what occurred along the
northwest Gulf coast.

This is last advisory issued by the National Hurricane Center on
Harvey. Future information on this system can be found in public
advisories issued by the Weather Prediction Center beginning at 4 AM
CDT under AWIPS header TCPAT4, WMO header WTNT34 KWNH, and on the
web at http://www.wpc.ncep.noaa.gov. Additional information can
also be found in products issued by your local National Weather
Service office.

The National Hurricane Center would like to thank all the men and
women that have worked countless hours at local National Weather
Service Forecast offices along the Gulf coast providing life-saving
warnings and information during the past week, on top of preparing
their family and homes for the storm. The center would also like to
acknowledge the dedication of the Air Force and NOAA Hurricane
Hunter aircraft crews that flew numerous missions into Harvey. In
addition, NHC thanks the staff at the Weather Prediction Center,
who led efforts to coordinate forecasts of the historic
flooding event, NWS River Forecast Centers that provided flood
guidance, and the Storm Prediction Center, that coordinated tornado
forecasts.

Key Messages:

1. Ongoing catastrophic and life-threatening flooding will continue
across southeastern Texas. While the threat of heavy rains has
ended in the Houston/Galveston area, catastrophic and life-
threatening flooding will continue in and around Houston, Beaumont/
Port Arthur, and eastward into southwest Louisiana for the rest
of the week. Isolated storm totals have reached 50 inches over the
upper Texas coast, including the Houston/Galveston metropolitan
area. Please heed the advice of local officials. Do not attempt to
travel if you are in a safe place, and do not drive into flooded
roadways. Refer to products from your local National Weather
Service office and the NOAA Weather Prediction Center for more
information on the flooding hazard. A summary of rainfall totals
compiled by the Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

2. The flood threat has spread farther north and east, and

POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
East Texas and Extreme Western Louisiana. Remain well guarded against
life-threatening flood waters having additional devastating to
catastrophic impacts.
These impacts include:
    - Extreme rainfall flooding may prompt numerous evacuations and
      rescues.
    - Rivers and tributaries may overwhelmingly overflow their banks
      in many places with deep moving water. Small streams, creeks,
      canals, and ditches may become raging rivers. Flood control
      systems and barriers may become stressed.
    - Flood waters can enter numerous structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Numerous places where flood waters may cover escape
      routes. Streets and parking lots become rivers of raging water
      with underpasses submerged. Driving conditions become very
      dangerous. Numerous road and bridge closures with some weakened
      or washed out.

Potential impacts from the flooding rain are still unfolding across
parts of Central Louisiana. Remain well guarded against
life-threatening flood waters having possible limited impacts.

* WIND:
Little to no additional impacts are anticipated at this time
across SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 AM CDT (1500 UTC), the center of Tropical Storm Harvey was
located near latitude 30.5 North, longitude 93.3 West. Harvey is
moving toward the north-northeast near 8 mph (13 km/h) and this
general motion is expected to continue through Thursday. A turn
toward the northeast is expected Thursday night and Friday. On the
forecast track, the center of Harvey should move through
southwestern and central Louisiana today and tonight, then move
through northeastern Louisiana and northwestern Mississippi Thursday
and Thursday night.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Weakening is forecast during the next 48 hours as Harvey moves
farther inland, and the cyclone is expected to weaken to a tropical
depression tonight.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
mainly to the south of the center. During the past few hours,
there have been reports of wind gusts of 40-50 mph (65-80 km/h) in
southwestern Louisiana and southeastern Texas near Lake Charles,
Cameron, and Sabine Pass.

The minimum central pressure based on surface observations is
993 mb (29.33 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce additional rainfall
accumulations of 3 to 6 inches from southwestern Louisiana and the
adjacent border of eastern Texas northeastward into western
Tennessee and Kentucky through Friday with isolated amounts up to 10
inches. The threat of heavy rains has ended in the Houston/
Galveston area. However catastrophic and life threatening flooding
will continue in and around Houston, Beaumont/Port Arthur, eastward
into southwest Louisiana for the rest of the week. The expected
heavy rains spreading northeastward from Louisiana into western
Kentucky may also lead to flash flooding and increased river, small
stream flooding. DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED AREA IF
YOU ARE IN A SAFE PLACE. DO NOT DRIVE INTO FLOODED ROADWAYS. Please
see warnings and products issued by your local National Weather
Service office for additional information on this life-threatening
situation.

Elsewhere, the outer bands of Harvey are expected to produce
additional rainfall amounts of 3 to 6 inches over portions of the
central and eastern Gulf States and 2 to 4 inches farther north into
parts of the Tennessee Valley, Ohio Valley and southern Mid Atlantic
through Saturday. These rains may lead to flooding concerns across
these areas.

A list of preliminary rainfall observations compiled by the NOAA
Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide…

Holly Beach to Morgan City…2 to 4 ft
San Luis Pass to west of Holly Beach incl. Galveston Bay…1 to 3 ft
Morgan City to Grand Isle…1 to 3 ft

The deepest water will occur along the immediate coast near the
area of onshore winds. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Tropical storm conditions are occurring over portions of
the warning area along the coast and are likely to persist through
this afternoon.

SURF: Swells generated by Harvey are still affecting the coasts of
Texas and Louisiana. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult products
from your local weather office.

TORNADOES: A few tornadoes are possible today and tonight over
parts of Louisiana, Mississippi, southern Alabama, and southeast
Arkansas.

Tropical Storm Harvey Discussion Number 41
NWS National Hurricane Center Miami FL AL092017
1000 AM CDT Wed Aug 30 2017

Harvey has changed little in organization since landfall, with
satellite and radar data showing continued convective banding, most
notably in the northwestern quadrant. Winds gusts of 35-45 kt have
been reported over the coastal regions south of the center, and the
central pressure has risen only slightly to 993 mb. Based on these
data, the initial intensity remains 40 kt. It should be noted that
a large area of winds just below tropical-storm-force is occurring
over the Gulf of Mexico south of the coasts of south-central and
southeastern Louisiana.

Radar and surface observations indicate that the center of Harvey
moved northward for a period of several hours near landfall, but now
is resuming a north-northeastward motion of roughly 020/7. The
cyclone is located on the northwestern side of a mid-tropospheric
high, which should steer it north-northeastward and then
northeastward across the Lower Mississippi and Tennessee Valleys
during the next few days until the system dissipates.

Harvey should gradually weaken as it moves farther inland, with the
intensity expected to drop below tropical-storm strength shortly
after the 12 h point. Subsequently, the system should decay to a
remnant low by 72 h and dissipate completely by 96 h. The forecast
weakening will not eliminate the risk of continued heavy rainfall
and flooding along Harvey’s path, although the system’s faster
motion will prevent rainfall totals from being anywhere near what
occurred over southeastern Texas.

Key Messages:

1. Ongoing catastrophic and life-threatening flooding will continue
across southeastern Texas. While the threat of heavy rains has
ended in the Houston/Galveston area, catastrophic and life-
threatening flooding will continue in and around Houston,
Beaumont/Port Arthur, eastward into southwest Louisiana for the rest
of the week. Isolated storm totals have reached 50 inches over the
upper Texas coast, including the Houston/Galveston metropolitan
area. Please heed the advice of local officials. Do not attempt to
travel if you are in a safe place, and do not drive into flooded
roadways. Refer to products from your local National Weather Service
office and the NOAA Weather Prediction Center for more information
on the flooding hazard. A summary of rainfall totals compiled by
the Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

2. The flood threat has spread farther north and east, and
additional rainfall accumulations of 3 to 6 inches with isolated
amounts up to 10 inches are expected from southwestern Louisiana and
the adjacent border of eastern Texas northeastward into western
Kentucky through Friday. Please heed the advice of local officials
and refer to products from your local National Weather Service
office and the NOAA Weather Prediction Center for more information
on the flooding hazard in these areas.

Mesoscale Discussion 1600
NWS Storm Prediction Center Norman OK
0951 AM CDT Wed Aug 30 2017

Areas affected…Parts of east central and southeast Louisiana
through southern Mississippi

Concerning…Severe potential…Tornado Watch likely

Valid 301451Z – 301645Z

Probability of Watch Issuance…80 percent

SUMMARY…At least some risk for mainly isolated, relatively
short-lived tornadoes is already evident. The extent of this threat
remains a bit unclear, but it seems likely to increase into and
through early afternoon, particularly within a corridor across east
central and southeast Louisiana through much of southern
Mississippi, perhaps as far north as the I-20 corridor.

DISCUSSION…Beneath the lower/mid tropospheric dry slot to the east
of the remnant circulation center of Harvey, breaks in low-level
cloud cover are likely already allowing for an increase in boundary
layer instability in response to insolation. This should continue
into and through the midday hours, particularly within a narrow
plume of tropical boundary layer moisture (with surface dew points
of 75F+) wrapping across southeast Louisiana and Mississippi coastal
areas, into the vicinity of the surface cyclone center which
continues to slowly track north northeast of Lake Charles.

Within/across this corridor of richer boundary layer moisture
content, a southeasterly component to the near surface flow beneath
southerly 850 mb flow on the order of 40 kt is already contributing
to favorable hodographs for the development of substantive low-level
mesocyclones. As cells embedded within ongoing and developing bands
of convection pivoting around Harvey occasionally strengthen, the
risk for mainly isolated, brief tornadoes will probably increase as
the boundary layer undergoes further destabilization into and
through early afternoon.

   Areas affected...Coastal LA and southeast TX

   Concerning...Tornado Watch 474...

   Valid 282058Z - 282230Z

   The severe weather threat for Tornado Watch 474 continues.

   SUMMARY...The severe threat is expected to remain isolated, but a
   brief tornado cannot be ruled out.

   DISCUSSION...Substantial rain and storms have produced outflow and
   reinforced the front across much of the area with surface winds
   mainly out of the northeast. East to southeasterly winds do exist
   south of the main boundary, which currently exists near the coast.

   A line of storms extends from southwestern LA southward, with some
   cellular structures within. As these cells continue to train
   northward, they will encounter the surface front and may acquire
   rotation briefly with effective SRH on the order of 200 M2/s2.

   Farther west, storms over southeast TX are moving cyclonically
   northwestward around TC Harvey. Some of these cells may also contain
   a threat briefly as they cross the aforementioned boundary.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sat Aug 26 2017

For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on recently
downgraded Tropical Storm Harvey, located inland over eastern Texas.

1. An elongated area of low pressure stretching across north-central
Florida continues to produce a large area of disorganized
cloudiness and thunderstorms extending from the southwest coast of
Florida northeastward into the western Atlantic. Although
upper-level winds are not particularly conducive, this system has
the potential to become a tropical or subtropical depression
early next week after it moves off the northeast coast of Florida
on Sunday. The low is forecast to move close to the southeastern
coast of the United States and merge with a cold front by mid-week.
Regardless of tropical cyclone development, the low is expected to
cause increasing winds and rough surf along the coasts of Georgia
and the Carolinas through early next week. Heavy rain is also
expected to continue over portions of southern and central Florida
during the next day or two. Please refer to products from your local
National Weather Service forecast office for more information on
this system.
* Formation chance through 48 hours…medium…40 percent.
* Formation chance through 5 days…medium…50 percent.

2. A tropical wave over western Africa is forecast to emerge over the
far eastern Atlantic Ocean on Sunday. Environmental conditions are
forecast to be conducive for slow development by the middle of next
week while the wave moves westward about 20 mph.
* Formation chance through 48 hours…low…0 percent.
* Formation chance through 5 days…low…20 percent.

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for…
* Port Aransas to High Island Texas

A Tropical Storm Warning is in effect for…
* Baffin Bay to High Island Texas

A Storm Surge Warning means there is a danger of life-threatening
inundation from rising water moving inland from the coastline in the
indicated locations. For a depiction of areas at risk, please see
the National Weather Service Storm Surge Watch/Warning Graphic,
available at hurricanes.gov. This is a life-threatening situation.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 400 PM CDT (2100 UTC), the center of Tropical Storm Harvey was
located by Doppler radar near latitude 29.1 North, longitude 97.6
West. Harvey has been nearly stationary and little motion is
anticipated during the next few days.

Maximum sustained winds have decreased to near 65 mph (100 km/h)
with higher gusts. Additional weakening is expected during the
next day or two.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The estimated minimum central pressure is 990 mb (29.24 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce additional rain
accumulations of 15 to 25 inches over the middle and upper Texas
coast through Thursday. Isolated storm totals may reach around 40
inches in this area. Elsewhere during the same period, Harvey is
expected to produce total rain accumulations of 5 to 15 inches
farther south toward the lower Texas coast, farther west toward the
Texas Hill Country and southwest and central Louisiana. Rainfall of
this magnitude will cause catastrophic and life-threatening
flooding. A list of rainfall observations compiled by the NOAA
Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide…

Port Aransas to Sargent…4 to 7 ft
Sargent to High Island including Galveston Bay…2 to 4 ft
High Island to Morgan City…1 to 2 ft

The deepest water will occur along the immediate coast near the
area of onshore winds, where the surge will be accompanied by large
and destructive waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Tropical storm conditions are occurring in portions of
the tropical storm warning area, and are likely to persist along
portions of the coast through at least Sunday.

SURF: Swells generated by Harvey are affecting the Texas,
Louisiana, and northeast Mexico coasts. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

TORNADOES: A few tornadoes are possible through Monday near the
middle and upper Texas coast into far southwest Louisiana.

============================================================================

 

Tropical Storm Harvey Discussion Number 26
NWS National Hurricane Center Miami FL AL092017
400 PM CDT Sat Aug 26 2017

Harvey has continued to weaken while located inland over Texas.
Doppler radar data indicate that winds are now 55 kt, and since
there are no surface observations near the center, this is the
intensity used in this advisory. A continued weakening is
anticipated, and the NHC forecast uses the trend provided by the
SHIPS decay model. However, if a large portion of Harvey’s
circulation remains over the Gulf of Mexico, the cyclone could
weaken at a slower rate than shown here.

Harvey has barely moved during the past few hours and little motion
is anticipated. Since the steering currents are forecast to remain
light, Harvey could easily meander for the next 4 to 5 days over
southeast Texas as indicated in the NHC forecast. Guidance disagrees
in which direction the cyclone will move, but all the models agree
that any motion will be quite slow.

 

Key Messages:

1. While Harvey’s winds are decreasing, life-threatening hazards
will continue from heavy rainfall over much of southeastern
Texas and from storm surge along portions of the Texas coast.

2. Catastrophic and life-threatening flooding is expected across the
middle and upper Texas coast from additional rainfall of 15 to
25 inches, with isolated storm totals as high as 40 inches, through
Thursday. Please heed the advice of local officials and do not
drive into flooded roadways. Refer to products from your local
National Weather Service office and the NOAA Weather Prediction
Center for more information on the flooding hazard. A summary of
rainfall totals compiled by the Weather Prediction Center can be
found at: http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

3. A Storm Surge Warning remains in effect for portions of the
Texas coast. Life-threatening storm surge flooding will be slow to
recede due to the slow motion of Harvey and a prolonged period of
onshore flow. For a depiction of areas at risk, see the Storm Surge
Watch/Warning Graphic at hurricanes.gov.

518 AM CDT Sat Aug 26 2017

This Hazardous Weather Outlook is for portions of central
Louisiana, south central Louisiana, southwest Louisiana, west
central Louisiana, and southeast Texas.

.DAY ONE...Today and Tonight
Harvey made landfall last night and has moved inland very slowly.
The majority of the rainbands continue across the central Texas
coast with this region this morning getting brushed but the outer
bands. A Tornado Watch continues for Jefferson... Hardin... and
Orange counties in southeast Texas. Rains will continue through
the day and into tonight.

.DAYS TWO THROUGH SEVEN...Sunday through Friday
Harvey is expected to bring bands of showers and isolated
thunderstorms across the region through the weekend and into next
week. Rainfall will be heavy at times and flooding of some
locations is expected.

.SPOTTER INFORMATION STATEMENT...

 

Harvey is getting an attitude now!

The Pressure took a precipitous drop and this system is a major Hurricane with winds sustained at 95kts/110mph.

NWS National Hurricane Center Miami FL AL092017
1000 AM CDT Fri Aug 25 2017

Multiple observing platforms indicate that Harvey’s structure is
evolving this morning. The hurricane has developed concentric
eyewalls, as observed in data from the WSR-88D Doppler radars in
Brownsville and Corpus Christi, and an Air Force Reserve Hurricane
Hunter plane reported double wind maxima with diameters of 12 and
28 n mi. The aircraft data indicate that the central pressure has
continued to fall–now down to 947 mb–but the maximum winds have
not increased further. This discrepancy is not surprising given
hurricane’s current structure.

Intensity forecasts become complicated once a hurricane develops
concentric eyewalls, and fluctuations in intensity become more
likely. If an eyewall replacement occurs, then Harvey’s intensity
could decrease a bit while at the same time the overall wind field
increases in size. However, the hurricane remains in an environment
for intensification, and strengthening beyond the current intensity
is still possible before the center reaches land. But in the end,
the hurricane’s exact intensity at landfall does not change the
fact that catastrophic flooding due to a prolonged period of heavy
rainfall and/or storm surge is expected at the coast and well inland
across much of southern and southeastern Texas. Slow weakening is
expected after Harvey crosses the coast since the center is not
expected to move very far inland, and the cyclone is likely to
maintain tropical storm status through Wednesday.

Harvey has not quite begun to slow down, and the initial motion
estimate is 315/9 kt. Strong mid-level ridging building over the
western United States is still expected to impede Harvey’s forward
motion in the coming days, and the track guidance continues to show
the hurricane meandering or stalling near or just inland of the
Texas coast in 36-48 hours. Harvey could begin moving slowly
eastward on days 4 and 5 due to the influence of a mid-level
shortwave trough digging southward over the upper Midwest, but at
this time it is too early to say whether the center will definitely
re-emerge over the northwestern Gulf of Mexico.

Key Messages:

1. Harvey is expected to be a major hurricane when it makes landfall
tonight, bringing life-threatening storm surge, rainfall, and wind
hazards to portions of the Texas coast. Preparations should be
rushed to completion in the warning areas as tropical-storm-force
winds are arriving on the coast, and conditions will continue to
deteriorate through the rest of today and tonight.

2. A Storm Surge Warning is in effect for much of the Texas coast.
Life-threatening storm surge flooding could reach heights of 6 to 12
feet above ground level at the coast between the north entrance of
the Padre Island National Seashore and Sargent. For a depiction of
areas at risk, see the Storm Surge Watch/Warning Graphic at
hurricanes.gov. Due to the slow motion of Harvey and a prolonged
period of onshore flow, water levels will remain elevated for
several days.

3. Catastrophic and life-threatening flooding is expected across the
middle and upper Texas coast from heavy rainfall of 15 to 25 inches,
with isolated amounts as high as 35 inches, through Wednesday.
Please refer to products from your local National Weather Service
office and the NOAA Weather Prediction Center for more information
on the flooding hazard.

4. The Potential Storm Surge Flooding Map is available on the NHC
website. This product depicts a reasonable worst-case scenario –
the amount of inundation that has a 10 percent chance of being
exceeded at each individual location. This map best represents
the flooding potential in those locations within the watch and
warning areas.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1000 AM CDT (1500 UTC), the eye of Hurricane Harvey was located
by an Air Force Reserve Hurricane Hunter aircraft and NOAA Doppler
radar near latitude 26.7 North, longitude 96.0 West. Harvey is
moving toward the northwest near 10 mph (17 km/h), but its forward
speed is expected to decrease significantly during the next couple
of days. On the forecast track, Harvey will make landfall on the
middle Texas coast tonight or early Saturday. Harvey is then likely
to meander near or just inland of the middle Texas coast through the
weekend.

Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts. Some strengthening is possible, and Harvey is forecast to
become a major hurricane before it reaches the middle Texas coast.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center, and tropical-storm-force winds extend outward up to 140
miles (220 km).  A buoy located about 40 miles east of South Padre
Island recently reported sustained winds of 42 mph (68 km/h) and a
gust to 54 mph (86 km/h).

The minimum central pressure based on data from the Air Force plane
is 947 mb (27.97 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Harvey is expected to produce total rain accumulations
of 15 to 25 inches and isolated maximum amounts of 35 inches over
the middle and upper Texas coast through next Wednesday.  During
the same time period Harvey is expected to produce total rain
accumulations of 5 to 15 inches in far south Texas and the Texas
Hill Country over through southwest and central Louisiana.  Rainfall
of this magnitude will cause catastrophic and life-threatening
flooding.

STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide...

N Entrance Padre Island Natl Seashore to Sargent...6 to 12 ft
Sargent to Jamaica Beach...5 to 8 ft
Port Mansfield to N Entrance Padre Island Natl Seashore...5 to 7 ft
Jamaica Beach to High Island...2 to 4 ft
Mouth of the Rio Grande to Port Mansfield...2 to 4 ft
High Island to Morgan City...1 to 3 ft

The deepest water will occur along the immediate coast near and to
the northeast of the landfall location, where the surge will be
accompanied by large and destructive waves.  Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances.  For information specific to
your area, please see products issued by your local National Weather
Service forecast office.

WIND:  All last-minute preparations should be rushed to completion
since tropical storm conditions are likely just beginning in
portions of the hurricane and tropical storm warning areas.
Hurricane conditions are likely to begin within the hurricane
warning area later today or tonight.  Tropical storm conditions are
likely to persist along portions of the coast through at least
Sunday.

SURF:  Swells generated by Harvey are affecting the Texas,
Louisiana, and northeast Mexico coasts.  These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

TORNADOES:  A few tornadoes are possible later today through
Saturday near the middle and upper Texas coast.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 PM CDT (0300 UTC), the center of Hurricane Harvey was
located near latitude 25.2 North, longitude 94.6 West. Harvey is
moving toward the northwest near 10 mph (17 km/h). This general
motion is expected to continue with a decrease in forward speed
during the next couple of days. On the forecast track, Harvey will
approach the middle Texas coast on Friday and make landfall Friday
night or early Saturday. Harvey is then likely to stall near or
just inland of the middle Texas coast through the weekend.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds remain near 85 mph (140 km/h)
with higher gusts. While Harvey has changed little in strength over
the past several hours, strengthening is expected to resume later
tonight, and Harvey is expected to become a major hurricane by
Friday before it reaches the middle Texas coast.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
(165 km).

The latest minimum central pressure reported by the Hurricane
Hunter aircraft is 973 mb (28.74 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce total rain accumulations
of 15 to 25 inches and isolated maximum amounts of 35 inches over
the middle and upper Texas coast through next Wednesday. During
the same time period Harvey is expected to produce total rain
accumulations of 7 to 15 inches in far south Texas and the Texas
Hill Country eastward through central and southwest Louisiana, with
accumulations of up to 7 inches extending into other parts of Texas
and the lower Mississippi Valley. Rainfall from Harvey will cause
devastating and life-threatening flooding.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide…

N Entrance Padre Island Natl Seashore to Sargent…6 to 12 ft
Sargent to Jamaica Beach…5 to 8 ft
Port Mansfield to N Entrance Padre Island Natl Seashore…5 to 7 ft
Jamaica Beach to High Island…2 to 4 ft
Mouth of the Rio Grande to Port Mansfield…2 to 4 ft
High Island to Morgan City…1 to 3 ft

The deepest water will occur along the immediate coast near and to
the northeast of the landfall location, where the surge will be
accompanied by large and destructive waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances. For information specific to
your area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are likely within the hurricane warning
area late Friday and Friday night, with tropical storm conditions
expected to first reach the coast in the hurricane warning area
Friday. These conditions are likely to persist into Saturday in
portions of the hurricane and tropical storm warning area.

SURF: Swells generated by Harvey are likely to affect the Texas,
Louisiana, and northeast Mexico coasts by Friday. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

TORNADOES: Isolated tornadoes are possible across portions of the
middle and upper Texas coast on Friday.

Hurricane Harvey Discussion Number 19
NWS National Hurricane Center Miami FL AL092017
1000 PM CDT Thu Aug 24 2017

Harvey’s rapid intensification seems to have slowed for the moment,
as an eye seen earlier in satellite imagery has lost definition
during the past few hours. In addition, reports from an Air Force
Reserve Hurricane Hunter aircraft show that 700-mb flight level
winds are in the 75-80 kt range, with reliable surface wind
estimates from the Stepped Frequency Microwave Radiometer remaining
near 75 kt. The aircraft also reported that the central pressure
has slowly fallen to 973 mb inside the 16 n mi wide eye. Based on
these data, the initial intensity remains 75 kt, and this could be a
little conservative.

Harvey has turned a little to the left since the last advisory with
the initial motion now 315/9. A mid-level anticyclone over the
eastern Gulf of Mexico is expected to steer Harvey generally
northwestward with a decreasing forward speed for the next 36-48 h,
with the center now forecast to make landfall on the middle Texas
coast in about 36 h. This part of the new forecast track has been
nudged a little to the left based mainly on the initial position
and motion. After landfall, the cyclone is likely to get stuck
between the Gulf anticyclone and a stronger anticyclone over the
western United States, with little motion likely from 48-96 h.
A slow eastward motion appears likely by 120 h due to the influence
of a trough in the westerlies digging into the eastern United
States. There is some spread in the guidance at that time, with
the GFS showing Harvey drifting slowly eastward and the ECMWF
showing a faster motion. The new forecast track splits this
difference of 5-day forecasts and lies near the consensus models.

It is unclear why the intensification has slowed, although it is
possibly due to some dry air seen earlier wrapping around the north
side of the core convection. Otherwise, Harvey remains in an
favorable environment for further strengthening with low vertical
shear and high oceanic heat content. The intensity forecast will
use the scenario that rapid intensification will resume tonight,
with Harvey becoming a major hurricane before landfall in Texas.
After landfall, the intensity forecast is based on the scenario that
Harvey will weaken over land, but it will remain close enough to
the coast so that the weakening will be slower than normal. Thus,
the forecast keeps Harvey as a tropical storm from 72-120 h.

It is critical that users not focus on the exact forecast track
of Harvey, since cycle-to-cycle adjustments are likely. All
locations within the hurricane and storm surge warning areas should
be preparing for the possibility of major hurricane-force winds and
life-threatening storm surge.

Key Messages:

1. Harvey is expected to be a major hurricane at landfall, bringing
life-threatening storm surge, rainfall, and wind hazards to portions
of the Texas coast. Preparations to protect life and property should
be completed by tonight, as tropical-storm-force winds will first
arrive in the hurricane and storm surge warning areas on Friday.

2. A Storm Surge Warning is in effect for much of the Texas coast.
Life-threatening storm surge flooding could reach heights of 6 to 12
feet above ground level at the coast between the north entrance of
the Padre Island National Seashore and Sargent. For a depiction of
areas at risk, see the Storm Surge Watch/Warning Graphic at
hurricanes.gov.

3. Devastating and life-threatening flooding is expected across the
middle and upper Texas coast from heavy rainfall of 15 to 25 inches,
with isolated amounts as high as 35 inches, from Friday through next
Wednesday. Please refer to products from your local National Weather
Service office and the NOAA Weather Prediction Center for more
information on the flooding hazard.

4. The Potential Storm Surge Flooding Map is available on the NHC
website. This product depicts a reasonable worst-case scenario –
the amount of inundation that has a 10 percent chance of being
exceeded at each individual location. This map best represents
the flooding potential in those locations within the watch and
warning areas.

Please review data in the link above.  It can provide context and a lot of this has been changing.  A lot of really good information and it gives are more detailed and user-friendly.    Give it a try and keep in mind your local Emergency Management, local radio and TV resources.  TSgt McClish can elaborate as well,  or myself, time permitting. Geeze dude, things are changing fast. We used to plot LAT/LONG and our best guess is those forecast points.

Meteorologist Larry Olson (Mike Scott) <– airname…

 

Harvey – 85mph Sustained.

I have seen Hurricane Harvey drop from 1007mb down to 979mb.  This deepening is a very big issue as Hurricane Harvey roars northwest.  From the southern most tip of Texas to Louisiana will experience the effects of a powerful (Major Hurricane).

It had stopped and that is never really a good thing.  Stay tuned to your scanners and local Radio and TV weather men and women.  Also consider the commentary as a rule of thumb.  When it does strike land,  and the areas around the circumference will get the worst of the severe weather.  Waterspouts and Tornados and wind damage all around Harvey.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 100 PM CDT (1800 UTC), the eye of Hurricane Harvey was located
by reconnaissance aircraft near latitude 24.4 North, longitude 93.6
West. Harvey is moving toward the north-northwest near 10 mph (17
km/h). A turn toward the northwest is expected later today, and
Harvey’s forward speed is forecast to slow down during the next
couple of days. On the forecast track, Harvey will approach the
middle Texas coast on Friday and make landfall Friday night or early
Saturday, and then stall near the middle Texas coast through the
weekend.

Data from Air Force Reserve and NOAA Hurricane Hunter aircraft
indicate that maximum sustained winds have increased to near 85 mph
(140 km/h) with higher gusts. Additional rapid strengthening is
forecast, and Harvey is expected to become a major hurricane by
Friday before it reaches the middle Texas coast.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center, and tropical-storm-force winds extend outward up to 90 miles
(150 km).

Data from the NOAA Hurricane Hunter plane indicate that the minimum
central pressure is 979 mb (28.91 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce total rain accumulations of
12 to 20 inches and isolated maximum amounts of 30 inches over the
middle and upper Texas coast through next Wednesday. During the same
time period Harvey is expected to produce total rain accumulations
of 5 to 12 inches in far south Texas and the Texas Hill Country to
central Louisiana, with accumulations of less than 5 inches
extending into other parts of Texas and the lower Mississippi
Valley. Rainfall from Harvey may cause life-threatening flooding.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide…

N Entrance Padre Island Natl Seashore to Sargent…6 to 12 ft
Sargent to Jamaica Beach…5 to 8 ft
Port Mansfield to N Entrance Padre Island Natl Seashore…5 to 7 ft
Jamaica Beach to High Island…2 to 4 ft
Mouth of the Rio Grande to Port Mansfield…2 to 4 ft
High Island to Morgan City…1 to 3 ft

The deepest water will occur along the immediate coast near and to
the northeast of the landfall location, where the surge will be
accompanied by large and destructive waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances. For information specific to
your area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are likely within the hurricane warning
area late Friday or Friday night, with tropical storm conditions
expected to first reach the coast in the hurricane warning area
Friday.

SURF: Swells generated by Harvey are likely to affect the Texas,
Louisiana, and northeast Mexico coasts by Friday. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 700 PM CDT (0000 UTC), the center of Tropical Depression Harvey
was located near latitude 21.7 North, longitude 92.5 West. The
depression is moving erratically toward the northwest near 2 mph (4
km/h). A track toward the northwest or north-northwest at a faster
forward speed is expected for the next 48 hours. On the forecast
track, Harvey should be approaching the Texas coast late Friday.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds remain near 35 mph (55 km/h)
with higher gusts. Some strengthening is forecast during the next
48 hours, and Harvey could become a tropical storm later tonight
and a hurricane on Friday.

The minimum central pressure estimated from the Hurricane Hunter
aircraft data and Mexican surface observations is 1003 mb
(29.62 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce total rain accumulations of
10 to 15 inches with isolated maximum amounts of 20 inches over the
middle and upper Texas coast and southwest Louisiana through next
Tuesday, with heavy rainfall beginning as early as Friday morning.
Harvey is also expected to produce total rain accumulations of 3 to
9 inches in portions of south, central, and northeast Texas and the
rest of the lower Mississippi Valley. Rainfall from Harvey could
cause life-threatening flooding.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide…

Port Mansfield to High Island…4 to 6 ft

The deepest water will occur along the immediate coast near and to
the northeast of the landfall location, where the surge will be
accompanied by large and destructive waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances. For information specific to
your area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are possible within the hurricane watch
area by late Friday, with tropical storm conditions possible by
early Friday.

SURF: Swells generated by Harvey are likely to affect the Texas,
Louisiana, and northeast Mexico coasts by Friday. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Tropical Depression Harvey Discussion Number 13
NWS National Hurricane Center Miami FL AL092017
400 PM CDT Wed Aug 23 2017

High-resolution visible satellite images show that the cloud pattern
of Harvey is a little better organized than it was this morning, but
the system lacks distinct banding features. Surface synoptic
observations, ASCAT data, and Dvorak classifications from TAFB and
SAB indicated that the cyclone has not strengthened, so the current
intensity is held at 30 kt. The global models predict that an
upper-level low over the northwest Gulf of Mexico will essentially
dissipate in a day or so. Therefore, Harvey is expected to remain
in a relatively low-shear environment up to the Texas coast.
Moreover, ocean analyses show that a warm eddy that broke off from
the Loop Current has drifted westward across the Gulf to a location
near the projected path of Harvey. This would also be conducive to
strengthening, so it is likely that the system will become a
hurricane prior to landfall, although this is not explicitly shown
in the NHC forecast for which landfall is indicated between 48 and
72 hours.

Based on the scatterometer data and geostationary satellite fixes
the center hasn’t moved much this afternoon, although recent imagery
suggests a northwestward drift at about 320/2 kt. A weak mid-level
ridge to the northeast of Harvey should cause the cyclone to move
on a northwestward or north-northwestward track through 48 hours.
Later, steering currents weaken as a ridge builds over the
southwestern United States and a trough drops down from the Plains.
As a result, Harvey should decelerate while making landfall and
move very slowly just inland of the coast. Some of the track
guidance models, such as the HWRF, have shifted southwestward in
comparison to their previous run. The official track forecast is
very close to the previous one through 48 hours and is a little
slower and to the west after that time. This is very close to the
latest dynamical model consensus, TVCN. It should be noted that
synoptic surveillance data are currently being collected by the NOAA
G-IV jet aircraft and these data will be assimilated into, and
hopefully improve the forecasts by, the global models.

Key Messages:

1. Harvey is likely to bring multiple hazards, including heavy
rainfall, storm surge, and possible hurricane conditions to portions
of the Texas coast beginning on Friday.

2. Heavy rainfall is likely to spread across portions of eastern
Texas, Louisiana, and the lower Mississippi Valley from Friday
through early next week and could cause life-threatening flooding.
Please refer to products from your local National Weather Service
office and the NOAA Weather Prediction Center for more information
on the flooding hazard.

3. A Storm Surge Watch is in effect from Port Mansfield to High
Island, Texas, indicating the possibility of life-threatening
inundation from rising water moving inland from the coast during the
next 48 hours. For a depiction of areas at risk, see the Storm
Surge Watch/Warning Graphic at hurricanes.gov.

4. The Potential Storm Surge Flooding Map is available on the NHC
website. This product depicts a reasonable worst-case scenario –
the amount of inundation that has a 10 percent chance of being
exceeded at each individual location. Because the Flooding Map is
based on inputs that extend out only to about 72 hours, it best
represents the flooding potential in those locations within the
watch area.

More fun With Harvey

Ole Harvery is a stubborn and vexing system.   I like the caveat “In any case, it will cause heavy rain”.   Captain Obious has that right. lol.    The heavy rain-maker is a given anyhow.    Oddly enough there has been some Anti-Cyclonic in the Central Gulf of Mexico.

With some of that cloudiness disappearing and convection being to fire up, it is something to be mindful of. Harvey will experience some drag over the Yucatan Peninsula.   It’s strength and trajectory in the next 1-2 days will affect this sys

I am still leaning towards a strong Tropical Wave or System (depression)  Maybe  it needs an SSRI. Smh.

Disturbance two will form over Florida and most of that will veer away causing only winds, rains and high surf.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Tue Aug 22 2017

For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

1. Disorganized showers and thunderstorms over the Yucatan Peninsula
and adjacent water areas are associated with the remnants of Harvey.
Environmental conditions are expected to be conducive for
development when the system moves over the Bay of Campeche tonight,
and a tropical depression is expected to form over the southwestern
Gulf of Mexico on Wednesday or Thursday. Regardless of development,
locally heavy rainfall and gusty winds are expected to spread
westward across Belize and the Yucatan Peninsula during the next day
or so. Interests in northeastern Mexico and along the Texas coast
should monitor the progress of this system.
* Formation chance through 48 hours…high…70 percent.
* Formation chance through 5 days…high…90 percent.

2. Shower and thunderstorm activity associated with a broad trough of
low pressure near the northwestern Bahamas remains limited. Any
development of this system during the next few days should be slow
to occur while it moves west-northwestward, and then turns
northwestward or northward near Florida and the adjacent waters.
Environmental conditions could become a little more conducive for
development by the weekend when the system begins to move
northeastward over the western Atlantic.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…30 percent.


Tropical Weather Discussion
NWS National Hurricane Center Miami FL
638 AM EDT Tue Aug 22 2017

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through 
1015 UTC.

...SPECIAL FEATURES...

A tropical wave extends from 24N87W to 13N88W moving W-NW at 
10-15 kt. The remnant circulation of Harvey continues to be 
analyzed as a 1011 mb low pressure along the wave axis near 
18N88W. Scattered moderate to isolated strong convection is from 
18N-23N between 79W-89W. Satellite images and surface 
observations indicates the low is along the coast of N Belize. 
Tropical cyclone development is expected when the system moves 
over the Bay of Campeche tonight or early Wednesday, and a 
tropical depression is likely to form over the southwestern Gulf 
of Mexico on Wednesday or Thursday. Regardless of development, 
locally heavy rainfall and gusty winds are expected to spread 
westward across Belize and the Yucatan peninsula during the next 
day or so. There is a high chance for this system to become a 
tropical cyclone within 48 hours. 

...TROPICAL WAVES...

A tropical wave extends from 24N29W to 10N32W moving W at 15-20 
kt. A 1011 mb low pressure precedes the wave centered near 
12N38W. Scattered moderate convection is from 09N-14N between 
25W-33W. This wave in a moist area based on TPW imagery and has a
well pronounced 700 mb trough.

A tropical wave extends from Puerto Rico near 19N67W to Venezuela
near 10N68W, moving W at 20-25 kt. Isolated showers are within 120
nm of the wave axis. Subtle troughing is noted on 700 mb streamline
analysis. Some moisture is observed on either side of the wave 
axis based on the SSMI TPW animation. This wave will cross the 
central Caribbean through mid-week.

...ITCZ/MONSOON TROUGH...

The monsoon trough extends from 18N16W to 18N27W to 12N38W to 
07N42W to 07N46W. The Intertropical Convergence Zone axis 
continues from 07N46W to 06N58W. Besides the convection mentioned
in the tropical wave section, scattered moderate to isolated
strong convection is along the coast of W Africa from 08N-14N 
between 12W-17W. Isolated moderate convection is from 05N-08N 
between 35W-43W.

...DISCUSSION...

GULF OF MEXICO...

Weak surface ridging is over the Gulf of Mexico with axis along
30N. 10-15 kt easterly surface flow is over the N Gulf. The
northern extent of a tropical wave is producing scattered moderate
to isolated strong convection over the SE Gulf of Mexico, Yucatan
Channel, and the N Yucatan Peninsula. Scattered showers and 
isolated thunderstorms are also advecting over S Florida from the 
Atlantic. In the upper levels, an upper level low is centered over
the W Gulf near 27N91W enhancing showers. Expect over the next 24
hours for the upper level low to remain quasi-stationary and 
continue to produce showers. Looking ahead, the remnant low of 
Harvey and tropical wave, will traverse the Yucatan Peninsula 
today, and then move into the Bay of Campeche Wednesday, where 
redevelopment to a tropical cyclone appears likely.

CARIBBEAN SEA...

The remnant low of Harvey currently located over N Belize continues
to be the primary area of concern across the basin. Please, see 
Special Features section for more details. A tropical wave is over
the eastern Caribbean. Please, see the Tropical Waves section for
details. Patches of low-level moisture embedded in the trade wind
flow are noted over parts of the east and central Caribbean. 
Fresh SE winds are observed per scatterometer data across the 
central Caribbean, but mainly N of 13N. These winds are the result
of the pressure gradient between the Atlantic ridge and the 
remnant low of Harvey. 

...HISPANIOLA...

Presently, showers are over SW Haiti. However,daytime heating, 
local sea breezes and mountain upslope lifting will combined with 
available moisture to produce scattered showers and thunderstorms
during the afternoon and evening hours today. The next tropical 
wave is forecast to pass just south of the island tonight into 
Wednesday.

ATLANTIC OCEAN...

A trough of low pressure continues to move westward across the
Bahamas and now extends from 29N77W across the N Bahamas to
central Cuba near 22N79W. This system continues to produce 
disorganized showers and thunderstorms, with fresh to strong winds
mainly on its NW side based on scatterometer data. Only slow 
development of this system is anticipated today while it moves 
west-northwestward towards Florida. Farther east, there is 
another surface trough that extends 24N55W to 16N55W. Scattered
moderate convection is from 23N-25N between 51W-54W. An upper- 
level low is also centered near 27N59W. A 1022 mb high is centered
W of Bermuda near 32N72W. Another 1022 mb high is centered over
the central Atlantic near 32N48W. The tail end of a cold front is
