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

The center of tropical Storm Harvey has moved slowly south over the
last 6 hours. Currently, the center of the circulation is located near
Goliad, Texas or 30 kilometers east of Victoria, Texas. The center is
moving to the east-southeast at 3 mph.

Our life-threatening flood event is ongoing east of the I-35 corridor.
Specifically for Bastrop, Caldwell, DeWitt, Fayette, Gonzales, Lavaca,
and Lee counties. A Flash Flood Warning is still valid for these
counties as roads are closed county wide in these areas. Since Friday
morning, widespread observed rainfall totals of 10-18 inches have
occurred east of Interstate 35. Isolated totals as high as
18-22 inches have fallen across Bastrop and Fayette counties.

Additional rainfall totals of 3-8 inches with isolated areas of
10 inches are still anticipated in these areas. Across Travis County,
including the city of Austin, 1 to 3 inches of rain with isolated
amounts up to 4 inches is anticipated through Wednesday evening. The
city of San Antonio has been bisected by the heavy rainfall, being on
the western extent of the rain shield and largely missing out on the
heaviest rainfall. Only about an inch of rain is anticipated for the
city of San Antonio through Wednesday evening.

Winds will gust to 30-45 mph tonight in the area under the counties
remaining under the tropical storm warning. Elsewhere wind gusts will
be 20-30 mph.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
areas mainly in Bastrop, Caldwell, DeWitt, Fayette, Gonzales, Lavaca,
and Lee counties. Remain well guarded against life-threatening flood
waters having additional devastating 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, arroyos, and ditches may become raging rivers. In
      mountain areas, deadly runoff may rage down valleys while
      increasing susceptibility to rockslides and mudslides. 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.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
tropical storm warning. Remain well sheltered from hazardous wind
having additional limited impacts. If realized, these impacts include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

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

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

* OTHER PREPAREDNESS INFORMATION:
Now is the time to remain safely sheltered from the storm. Stay inside
and away from windows. Listen for updates and be ready in case you
lose electrical power. Locate your battery powered radio and flashlight
from your Emergency Supplies Kit. Keep these items close.

Continue to keep your cell phone well charged for as long as possible.
If you lose power, use it more sparingly and mainly for personal
emergencies and check-ins. Do not overload communications systems with
idle chatter.

Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.

Be ready to move to the identified safe room if your home or shelter
begins to fail. Quickly move to an interior room on the lowest floor.
Put as many sturdy walls between you and the storm as you can.
Protect your head and body.
