----------------------------------------------
LOCATION...22.6N 92.6W
ABOUT 465 MI...740 KM SSE OF PORT OCONNOR TEXAS
ABOUT 410 MI...660 KM SE OF PORT MANSFIELD TEXAS
MAXIMUM SUSTAINED WINDS...45 MPH...70 KM/H
PRESENT MOVEMENT...NW OR 325 DEGREES AT 7 MPH...11 KM/H
MINIMUM CENTRAL PRESSURE...1001 MB...29.56 INCHES


WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Watch is in effect for...
* Port Mansfield to High Island

A Hurricane Watch is in effect for...
* North of Port Mansfield to San Luis Pass

A Tropical Storm Watch is in effect for...
* Boca De Catan Mexico to Port Mansfield Texas
* North of San Luis Pass to High Island

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.
For a depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at
hurricanes.gov.

A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Warnings will likely be required for portions of the watch area
this morning. 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 100 AM CDT (0600 UTC), the center of Tropical Storm Harvey
was located by NOAA and Air Force reconnaissance planes near
latitude 22.6 North, longitude 92.6 West. Harvey is now moving
toward the northwest near 7 mph (11 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 on Friday.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that the maximum sustained winds have increased to near 45
mph (70 km/h) with higher gusts. Some additional strengthening is
forecast during the next 48 hours, and Harvey could become a
a hurricane on Friday.

Tropical-storm-force winds extend outward up to 100 miles (160 km)
to the northeast of the center.

The latest minimum central pressure reported by Air Force and
NOAA Hurricane Hurricane Hunter planes was 1001 mb (29.56 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Harvey is expected to produce total rain accumulations of
10 to 15 inches and isolated maximum amounts of 20 inches over the
Texas coast and southwest Louisiana through next Wednesday, with
heavy rainfall beginning Friday. During the same time period Harvey
is expected to produce total rain accumulations of 3 to 9 inches
along its outer radius including parts of south, central, and
eastern 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...

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 late Friday or Friday night, with tropical storm conditions
possible by 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 1000 AM CDT (1500 UTC), the center of Tropical Storm Harvey was
located by an Air Force Reserve Hurricane Hunter aircraft near
latitude 24.0 North, longitude 93.3 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 the Hurricane Hunter plane indicate that maximum sustained
winds have increased to near 65 mph (100 km/h) with higher gusts.
Rapid strengthening is forecast, and Harvey is expected to become a
major hurricane before it reaches the middle Texas coast.

Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.

The minimum central pressure based on reconnaissance data is 982 mb
(29.00 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 10 ft
Sargent to San Luis Pass...5 to 7 ft
Port Mansfield to N Entrance Padre Island Natl Seashore...5 to 7 ft
San Luis Pass 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.

Storm surge coupled with this thing hanging in the same general area after landfall for maybe 72 hours before heading back out into the Gulf is setting up for a major disaster.

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.

This thing is rapidly developing. Not good for TX coast. Yesterday was just a threat of a lot of rain, now it will come ashore with high winds as well. I know that the weather service is afraid of "Cry Wolf" syndrome, but this one looks bad. No upper level winds, no dry air to suck in to it; who knows how strong it will get before land fall.

Really worried about this. We're talking about a potentially Allison-level rainfall event plus Cat 2-3 storm surge. Not good. Glad they've got evac orders underway; I saw that they were using city buses in Corpus Christi to take people to San Antonio, so hopefully that's a sign that public services, government, and forecasters are coordinating well here.

With an Elena type track on top of that.
