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.

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.

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.

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.

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 36 hours 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. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. A warning is typically issued
36 hours before the anticipated first occurrence of tropical-storm-
force winds, conditions that make outside preparations difficult or
dangerous. Preparations to protect life and property should be
rushed to completion.

A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the
coastline, in the indicated locations during the next 48 hours.

A Hurricane Watch means that hurricane conditions are possible
within the watch area.

In addition, interests in southwestern Louisiana should continue to
monitor the progress of this system.

For storm information specific to your area in the United
States, including possible inland watches and warnings, please
monitor products issued by your local National Weather Service
forecast office. For storm information specific to your area outside
the United States, please monitor products issued by your national
meteorological service.

 

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.
