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

Tropical Storm Hanna has developed now as the system continues to move
toward the Texas coast. An increase in organization has been noted and
Hurricane Hunter flight found an increase in wind speeds. The system
will approach the Texas coast Friday night with landfall on Saturday.
Forecast wind speeds have increased to high end tropical storm force
just before landfall. Strong winds will move inland through South
Texas during the day Saturday and into Saturday night.

The primary threat with this system remain the potential for very
heavy rainfall. Rainfall totals of 4 to 6 inches area wide are likely
with isolated amounts of up to 10 inches possible through Monday. The
heaviest rain will occur from Friday afternoon through Sunday. Minor
coastal flooding will be possible this weekend. Coastal inundation of
2 to 3 feet will be possible along beaches and bays of the Middle
Texas Coast.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across South Texas. Potential impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals,
      arroyos, and ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

* WIND:
Protect against dangerous wind having possible significant impacts
across the Southern Coastal Bend and Southern Brush Country. Potential
impacts in this area include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Also, protect against hazardous wind having possible limited impacts
across the rest of South Texas.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across the immediate Texas Coast and Bays. Potential impacts in this
area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

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

* EVACUATIONS:
Listen to local officials for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
