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

Tropical Storm Hanna continues to track westward early this morning.
Intensity remains unchanged with low end Tropical Storm force winds at
this time. Convection has increased around the center of circulation
early this morning. Hanna will approach the Texas coast Friday night
with landfall on Saturday. Hanna will be a strong Tropical Storm with
maximum wind gusts up to hurricane force. 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 8 inches are likely over the
Coastal Plains and eastern Brush Country with 2 to 5 inches farther
northwest. Isolated amounts of up to 12 inches are possible near the
track of the storm. The heaviest rain will occur from Friday night
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 most of 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.

Protect against locally hazardous rainfall flooding having possible
limited impacts across the northern Rio Grande Plains.

* 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 remainder of South Texas.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across 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.

* TORNADOES:
Protect against a tornado event having possible limited impacts across
the Coastal Bend. The occurrence of isolated tornadoes can hinder the
execution of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys
      toppled, mobile homes pushed off foundations or overturned,
      large tree tops and branches snapped off, shallow-rooted trees
      knocked over, moving vehicles blown off roads, and small boats
      pulled from moorings.

Elsewhere across South Texas, little to no impact is anticipated.

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

* EVACUATIONS:
Listen to local official 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
