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

At 400 PM CDT, the center of Tropical Storm Laura was
located near the Isle of Youth, south of Cuba. Laura is
moving toward the west-northwest near 20 mph, and this
general motion with some decrease in forward speed is expected over
the next day or so.  A turn toward the northwest is forecast by
Wednesday, and more north-northwesterly motion should
continue through Wednesday night.  On the forecast track, Laura is
forecast to approach the northwestern coast of the Gulf of
Mexico Wednesday night.

Maximum sustained winds are near 60 mph. Strengthening is expected
when the storm moves over the Gulf of Mexico, and Laura is forecast
to become a hurricane by late Tuesday. Additional strengthening is
forecast before landfall on Wednesday night. Specific impacts will be
strongly dependent on the exact track and intensity of the storm
when it makes landfall. Stay alert to the latest forecast information!
Adjustments to track may require additional watches or warnings further
down the Southeast Texas Gulf Coast.

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

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across Galveston Island and the Bolivar Peninsula. Potential impacts in
this area include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near-shore escape routes and secondary roads become
      weakened or washed out, especially in usually vulnerable low
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Also, prepare for locally hazardous surge having possible limited
impacts across other portions of the Southeast Texas Gulf Coast.


* WIND:
Prepare for life-threatening wind having possible extensive impacts
across the Bolivar Peninsula, and the east shore of Galveston Bay.
Potential impacts in this area include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Also, prepare for dangerous wind having possible limited to
significant impacts across portions of Southeast Texas.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts east of Galveston Bay. 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 much of Southeast Texas.

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

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

If evacuating, leave with a destination in mind
and allow extra time to get there. Take your emergency supplies kit.
Gas up your vehicle ahead of time.


* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.
