This hazardous weather outlook is for portions of Southeast Texas..

.DAY ONE...Today and Tonight

The National Hurricane Center is continuing to monitor the remnants
of tropical system Harvey, which is currently located over the
eastern Bay of Campeche, and is expected to move northwestward
over the western Gulf of Mexico. Environmental conditions are
favorable for development, and a tropical depression or tropical
storm is very likely to form today or tonight.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

The tropical system will move into the northwestern Gulf of
Mexico on Friday, and possibly slow down over the region. A slow
moving tropical system such as this can produce copious tropical
rainfall amounts. In the past, slow moving tropical systems have
produced amounts in excess of 20 inches leading to widespread
dangerous flooding. Tropical storm to hurricane force winds could
be possible, as well as tornadoes and storm surge. High tides
along the upper Texas Coast will likely cause impacts from
dangerous rip currents to storm surge flooding. The range of
possibilities with storm surge are varied given the highly
uncertain track of this system. Evacuations may be possible.

Marine impacts will include high winds and large dangerous seas
possible by Friday again depending on the strength and track of
the system.

Persons in Southeast Texas should be monitoring the weather
closely.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is likely at some point between Thursday night
and Monday.

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

.DAY ONE...Today and Tonight
Looking for showers and thunderstorms to develop this afternoon
continuing into this evening before dissipating. A cold front
moving through southern Arkansas is expected to move into
Louisiana making the coast around sunrise tomorrow.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday
Thursday will see a return of afternoon showers and thunderstorms.
The real change to our weather is Harvey which is in the Bay of
Campeche. The Hurricane Center expects Harvey to reform back into
a cyclone moving off to the northwest and guidance is suggesting
the storm will make landfall along the central Texas coast by
late Friday The system is expected to stall before moving towards
southeast Texas and into southern Louisiana. This is expected to
produce heavy rains over the weekend and into Monday. Rains are
expected to produce flooding in locations across the region. Five
to eight inches of rain is expected with some locations receiving
higher amounts.

This Hazardous Weather Outlook is for South-Central Texas..

.DAY ONE...Tonight.

Evening scattered thunderstorms are expected across the Hill
Country and Edwards Plateau, where isolated heavy rain and gusty
winds of 30 to 40 mph are possible as a frontal boundary stalls
over the region.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

Harvey is expected to move to the northwest and approach the
Texas coast Friday. The tropical system will bring tropical storm
winds and heavy rain across South Central Texas beginning Friday
and continuing into the weekend. There is a Tropical Storm Watch
for counties east of Interstate 35. Flash flooding and river
flooding is possible, mainly across the Tropical Storm Watch area.
Please refer to the NHC website (www.nhc.noaa.gov) and our local
office website (www.weather.gov/sanantonio) for latest information
and to follow the evolution of Harvey as it gets closer to the
Texas coast.

As of now, the storm total rainfall amounts of 6 to 10 inches are
expected east of Interstate 35 with isolated 12 inches across
counties in the Tropical Storm Watch from Friday afternoon through
Monday afternoon. It should be stressed that there is the
potential for much higher amounts across South Central Texas as
they will be highly dependent on the track and intensity of
Harvey.

There is a good chance for the issuance of a Flash Flood Watch
later tonight (overnight weather package) as the result of
rainfallamounts increasing. The FFW is likely for the areas
under the Tropical Storm Watch.

There is a low risk of brief tornadoes east of Interstate 35 Friday
evening into the weekend associated with tropical rain bands.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated at this time. However,
weather reports are welcome during the event on Friday into the
weekend.
