A Hurricane Watch is in effect for...
* South of Port Mansfield Texas to the Mouth of the Rio Grande

A Tropical Storm Watch is in effect for...
* South of the Mouth of the Rio Grande to Boca de Catan Mexico

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.

NEXT ADVISORY
-------------
Next intermediate advisories at 1200 AM CDT and 200 AM CDT.
Next complete advisory at 400 AM CDT.

Spotted this on the KIII stream. 10:00pm advisory is in and you can see how it will be a flood event when it makes landfall. It is just going to sit there. I really hope people are taking the warning seriously and getting out of town.

KoD · Aug 24, 2017

It's incredibly unfortunate that Harvey is expected to stall out right after landfall. This is shaping up to be a very bad flooding event.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 400 AM CDT (0900 UTC), the eye of Hurricane Harvey was located
near latitude 25.9 North, longitude 95.4 West. Harvey is moving
toward the northwest near 9 mph (15 km/h), and this general motion
is expected to continue 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 105 mph (165 km/h) with higher
gusts. Some strengthening is possible, and Harvey is expected to
become a major hurricane before it reaches the middle Texas coast.

Hurricane-force winds extend outward up to 25 miles (35 km) from the

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 700 AM CDT (1200 UTC), the eye of Hurricane Harvey was located
by Air Force Reserve reconnaissance aircraft and NOAA Doppler radar
near latitude 26.3 North, longitude 95.8 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 expected 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).

The minimum central pressure reported by the Air Force plane was 950
mb (28.05 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 later today and tonight, with tropical storm conditions
expected to first reach the coast in the hurricane warning area
later this morning. These conditions are likely to persist
into Saturday in portions of the hurricane and tropical storm
warning area.

SURF: Swells generated by Harvey will begin to affect the Texas,
Louisiana, and northeast Mexico coasts later this morning. 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 today.

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.

Noticed an increase in velocities on radar over the past half hour, I think we're on our way to major very soon.

WesL · Aug 25, 2017

944.5mb on that last pass into the eye by AF305

brandonburns03 · Aug 25, 2017

What's the projected path after the stall? Will it strengthens if it bounces back in the gulf and move up the coast toward Louisiana?

I always enjoy watching the Hurricane Hunters data as they fly in and around the Hurricanes.
