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.

WATCHES AND WARNINGS
——————–
CHANGES WITH THIS ADVISORY:

The Storm Surge Warning for the Texas coast south of Port Aransas
has been discontinued.

The Hurricane Warning for the Texas coast has been replaced with a
Tropical Storm Warning.

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

Hurricane warnings continue for inland areas near the center of
Harvey. Please see products from your local National Weather
Service office.

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.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning.

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 1000 AM CDT (1500 UTC), the center of Hurricane Harvey was
located near latitude 28.9 North, longitude 97.3 West. Harvey is
moving slowly toward the north near 2 mph (4 km/h), and little
motion is anticipated during the next several days.

Maximum sustained winds have decreased to near 75 mph (120 km/h)
with higher gusts. These winds are confined to a small area near the
center. Weakening is forecast during the next 48 hours, and Harvey
is expected to become a tropical storm this afternoon.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).

The estimated minimum central pressure is 984 mb (29.06 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce total rain accumulations of
15 to 30 inches and isolated maximum amounts of 40 inches over the
middle and upper Texas coast through Thursday. During the same
time period Harvey is expected to produce total rain accumulations
of 5 to 15 inches in far south Texas, 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 3 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: Hurricane conditions are occuring inland near the core
of Harvey. 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: Tornadoes are possible today and tonight near the middle
and upper Texas coast into far southwest Louisiana.

Hurricane Harvey Discussion Number 25
NWS National Hurricane Center Miami FL AL092017
1000 AM CDT Sat Aug 26 2017

Harvey has been inland for about 12 hours and weakening is under
way. Doppler radar data indicate that winds have decreased to 65 kt,
and that is the intensity used in this advisory. Since Harvey is
over land, a continued weakening is anticipated, and the NHC
forecast uses the trend provided by the SHIPS decay model. However,
if a portion of Harvey’s circulation remains over the Gulf of
Mexico, the cyclone could weaken at a slower rate than shown here.

The hurricane is moving very slowly toward the north at about 2 kt.
Harvey is embedded within very light steering currents, and global
models keep this weak flow in place for the next several days. Based
on this pattern, Harvey could easily meander for the next 4 to 5
days over southeast Texas as indicated in the NHC forecast. The only
agreement among the track guidance is that Harvey is certainly not
going anywhere fast.

This slow motion of the cyclone is expected to exacerbate the
potential for catastrophic flooding from heavy rainfall at least
through the middle of next week.

Please note that hourly Tropical Cyclone Updates (TCUs) have been
discontinued due to the degradation of Harvey’s center on radar.

Key Messages:

1. While Harvey’s winds have begun to weaken, 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 heavy rainfall of 15 to 30 inches,
with isolated amounts 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. 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.

SITUATION OVERVIEW
------------------

Hurricane Harvey remains a Category 1 hurricane over Goliad and
Victoria Counties where Hurricane Warning continues. Hurricane Warning
has been replaced with a Tropical Storm Warning for the coastal
counties of the Middle Texas coast, as well as the inland counties of
the Coastal Bend, and the coastal waters. Harvey will continue to move
slowly northwest today across South Texas and become a Tropical Storm.
Harvey will slow down and stall northwest of Cuero tonight and then
drift southeast back toward the coast Sunday through Tuesday.

Hurricane force wind gusts will continue to affect portions of Goliad
and Victoria counties, mainly through early this afternoon. Meanwhile,
tropical storm force winds will continue to impact portions of South
Texas generally east of Highway 281 for most of today.

Catastrophic life-threatening flooding is still expected due to the
heavy rainfall that is expected over the next several days. Storm
total rainfall accumulations will be as much as 20 to 30 inches of
rainfall with isolated 40 inches across eastern portions of South
Texas, mainly east of a line from Rockport to Goliad. West of that
area up to highway 16, generally 5 to 15 inches of rainfall will be
possible with isolated 20 inches possible. West of highway 16,
generally 5 inches or less of rainfall is expected.

Storm surge inundation will remain from 4 to 7 feet from Port Aransas
to Port Lavaca today. Flooding from storm surge inundation will
gradually subside through the day. South of Port Aransas, offshore
winds have provided a significant decrease in tide levels.

Isolated tornadoes will be possible along and to the east of a line
from Port Aransas to Beeville.

Mandatory evacuations are in effect for the following areas:

  - Port Aransas
  - Aransas County
  - Refugio County
  - San Patricio County
  - Victoria County
  - Calhoun County

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the Coastal Bend and Victoria Crossroads area, mainly east of Highway
281. Remain well guarded against life-threatening flood waters having
possible catastrophic impacts. If realized, 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.

* SURGE:
Impacts from the surge event are now unfolding across the Middle Texas
coast between Port Aransas and Port Lavaca. Tide inundation levels will
continue to be from 4 to 7 feet AGL. Remain well away from
life-threatening surge having additional extensive impacts. If
realized, these impacts include:
    - Large areas of deep inundation with storm surge flooding
      accentuated by battering waves. Structural damage to buildings,
      with several washing away. Damage compounded by floating
      debris. Locations may be uninhabitable for an extended period.
    - Large sections of near-shore escape routes and secondary roads
      washed out or severely flooded. Flood control systems and
      barriers may become stressed.
    - Severe beach erosion with significant dune loss.
    - Major damage to marinas, docks, boardwalks, and piers. Many
      small craft broken away from moorings, especially in
      unprotected anchorages with some lifted onshore and stranded.


* WIND:
Potential impacts from the main wind event are now unfolding across
the Coastal Bend and Victoria Crossroads area, mainly east of Interstate
37. If realized, these impacts include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Elsewhere across SOUTH TEXAS, little to no impact is anticipated.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across the
Victoria Crossroads. If realized, these impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys
      toppled, mobile homes pushed off foundations or overturned,
      large tree tops and branches snapped off, shallow-rooted trees
      knocked over, moving vehicles blown off roads, and small boats
      pulled from moorings.

Elsewhere across SOUTH TEXAS, little to no impact is anticipated.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:

RECOVERY PHASE - Do not return to evacuated areas until it is safe.
Listen for the all-clear signal from local authorities.

* ADDITIONAL SOURCES OF INFORMATION:
- For information on appropriate preparations see ready.gov
- For information on creating an emergency plan see getagameplan.org
- For additional disaster preparedness information see redcross.org

NEXT UPDATE
-----------

The next local statement will be issued by the National Weather
Service in Corpus Christi TX around 1 PM CDT, or sooner if conditions
warrant.

WATCHES AND WARNINGS
——————–
CHANGES WITH THIS ADVISORY:

The Storm Surge Warning for the Texas coast south of Port Aransas
has been discontinued.

The Hurricane Warning for the Texas coast has been replaced with a
Tropical Storm Warning.

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

Hurricane warnings continue for inland areas near the center of
Harvey. Please see products from your local National Weather
Service office.

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.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning.

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 1000 AM CDT (1500 UTC), the center of Hurricane Harvey was
located near latitude 28.9 North, longitude 97.3 West. Harvey is
moving slowly toward the north near 2 mph (4 km/h), and little
motion is anticipated during the next several days.

Maximum sustained winds have decreased to near 75 mph (120 km/h)
with higher gusts. These winds are confined to a small area near the
center. Weakening is forecast during the next 48 hours, and Harvey
is expected to become a tropical storm this afternoon.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).

The estimated minimum central pressure is 984 mb (29.06 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce total rain accumulations of
15 to 30 inches and isolated maximum amounts of 40 inches over the
middle and upper Texas coast through Thursday. During the same
time period Harvey is expected to produce total rain accumulations
of 5 to 15 inches in far south Texas, 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 3 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: Hurricane conditions are occuring inland near the core
of Harvey. 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: Tornadoes are possible today and tonight near the middle
and upper Texas coast into far southwest Louisiana.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 700 PM CDT (0000 UTC), the eye of Hurricane Harvey was located by
reconnaissance aircraft and NOAA Doppler radar near latitude 27.8
North, longitude 96.8 West. Harvey is moving toward the northwest
near 8 mph (13 km/h), but its forward speed is expected to decrease
during the next couple of days. On the forecast track, Harvey will
make landfall on the middle Texas coast during the next several
hours. Harvey is then likely to meander 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 130 mph
(215 km/h) with higher gusts. Harvey is a category 4 hurricane on
the Saffir-Simpson Hurricane Wind Scale. Little change in strength
is likely before landfall. Weakening is then expected over the
weekend while the center moves inland over Texas.

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 Texas Coastal Ocean Observing Network station at
Aransas Pass recently reported sustained winds of 79 mph (128 km/h)
and a wind gust of 101 mph (163 km/h).

The latest minimum central pressure reported by the Hurricane
Hunter aircraft is 941 mb (27.79 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce total rain accumulations of
15 to 30 inches and isolated maximum amounts of 40 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…

Port Aransas to Port O’Connor…9 to 13 ft
Elsewhere 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…3 to 5 ft
Jamaica Beach to High Island…2 to 4 ft
Mouth of the Rio Grande to Port Mansfield…1 to 3 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 occuring along the coast in
the Port Aransas area and should spread over other portions of the
hurricane warning area during the next several hours. Tropical
storm conditions are occurring in other portions of the hurricane
and tropical storm warning areas. 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 through Saturday near the
middle and upper Texas coast into far southwestern Louisiana.

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

Hurricane Harvey Discussion Number 22
NWS National Hurricane Center Miami FL AL092017
400 PM CDT Fri Aug 25 2017

Despite its concentric eyewall structure, Harvey’s winds have
increased during the day. NOAA and Air Force Reserve Hurricane
Hunter planes have measured maximum flight-level winds of 129 kt
and SFMR winds to 102 kt. Based on these data, Harvey’s maximum
surface winds are estimated to be 110 kt. Harvey’s central pressure
has also continued to fall, and the latest estimate based on
dropsonde data is 941 mb.

Harvey still has not slowed down, and the initial estimate is
325/9 kt. Based on the forecast track, Harvey is expected to make
landfall along the middle Texas coast tonight. After that, the
track models insist that the hurricane will slow down considerably
during the next 24 hours, and it is likely to move very little
between 36 and 120 hours. In fact, there has been a somewhat
notable change in the guidance, with very few of the models showing
Harvey lifting out toward the northeast by the end of the 5-day
forecast period. As a result, the NHC track forecast has been
pulled back a bit and keeps Harvey near or just inland of the Texas
coast through the middle of next week. This slow motion only
exacerbates the heavy rainfall and flooding threat across southern
and southeastern Texas.

Harvey may continue to strengthen during the 6-12 hours it has
before landfall, but regardless it is expected to make landfall at
major hurricane strength. Gradual weakening is anticipated after
the center moves inland, but Harvey’s slow motion will keep a
significant portion of its circulation over water, which may slow
the weakening rate. As a result, the NHC intensity forecast leans
closer to the global model guidance instead of the statistical-
dynamical guidance, which seems to weaken Harvey too fast. Harvey
could maintain tropical storm strength for the entire 5-day
forecast period due to its proximity to the northwestern Gulf of
Mexico.

Key Messages:

1. Harvey will make landfall tonight, bringing life-threatening
storm surge, rainfall, and wind hazards to portions of the Texas
coast. Tropical-storm-force winds have moved onshore in portions of
the warning areas and conditions will continue to deteriorate as
the eye of Harvey approaches the middle Texas coast 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 30 inches,
with isolated amounts as high as 40 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.

ATTN…WFO…BRO…CRP…EWX…HGX…

NOW LET ME BE PERFECTLY CLEAR.   THIS IS NO TIME TO BE AN EGGHEAD AND DRINK AND ACT A FOOT.    THIS IS A BAD ASS STORM!!!!

LISTEN TO EMT,  LOCAL RADIO AND TV SOURCES, including WX Channel and scanners.   Stay alive and be smart!

Well,  this is a crazy storm!!  It has deepened like a deep crevice opening, or a Caldera.   It WILL be nasty and it is going to ruin a lot of people’s lives.    This wv-animated (3)

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.
