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

Recent Air Force Hurricane Hunter aircraft indicated maximum sustained
winds around 45 mph in what was Tropical Depression Nine and has
therefore been upgraded and named Tropical Storm Harold. Harold is
located 195 miles east of Port Mansfield and quickly moving west-
northwest around 18 mph and is expected to make landfall on the South
Texas coast south of Baffin Bay midday Tuesday. Rain bands continue to
be confided to offshore areas. It'll be a few more hours before any
land area will see any notable rainfall, but coverage is expected to
increase around sunrise and continue through the evening, shifting
westward across South Texas. The main threats to South Texas on Tuesday
remain:

- Flash Flooding: Moderate threat of flash flooding mainly south and
west of I-37, especially in urban areas. Rainfall accumulations 3 to
5" with locally up to 7" through early Wednesday.

- Hazardous Seas: Wave heights 10 to 12 feet with occasionally up to
16 feet.

- Tornadoes: Isolated tornadoes are possible across South Texas,
especially in outer rain bands.

- Coastal Flooding: Moderate coastal flooding is expected with up to
3 ft of inundation possible across the Middle Texas Coast south of
Matagorda Bay.

- Rip Currents: High risk of rip currents across all of the Texas
Coast.

- Strong Winds: Tropical Storm force winds of sustained 40-50 mph with
gusts up to 60-70 mph are possible in the warned areas.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across southern Brush Country and southern Coastal Bend.
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, 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across northern portions of the Brush Country and the
rest of the Coastal Plains.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
South Texas. Potential impacts include:
    - 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.

* WIND:
Prepare for hazardous wind having possible limited impacts across the
Middle Texas coast and the inland Coastal Plains. Potential impacts
in this area 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 Texas, little to no impact is anticipated.

* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across the Middle Texas coast. 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:

WATCH/WARNING PHASE - 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.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which

attention for instructions from local authorities.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
