As of 10 AM CDT, Tropical Storm Beta remains in the northwestern Gulf
of Mexico and continues to move slowly to the northwest. The latest
satellite imagery indicates that the system has taken a more westward
turn this morning. This motion is expected to continue through tomorrow
and into the early part of next week as it approaches the middle Texas

This has the potential to become a prolonged coastal flooding event
for the SE Texas coast. Beta continues to pose the threat of dangerous
storm surge, as well as the possibility of flooding rains and hurricane
force wind gusts. The combination of storm surge and heavy rainfall
along with high tides will elevate the risk of dangerous flooding along
the Barrier Islands and inner coastal locations through mid-week.


Prepare for locally hazardous surge having possible limited impacts
across the Barrier Islands and coastal regions from Matagorda
Bay through Galveston Bay. Potential impacts in this area
- 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.
- 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.

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

Prepare for dangerous rainfall flooding having possible significant
impacts across along and south of Interstate 10. Potential impacts
- Moderate rainfall flooding may prompt several evacuations and
- 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.

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

Prepare for life-threatening wind having possible extensive impacts
along the Texas Coast. Potential impacts in this area
- 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 most of Southeast Texas.


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

* Galveston County has issued a voluntary evacuation order for the
Bolivar Peninsula. Residents of this area who have medical needs
should consider finding alternate accommodations in case the area
becomes inaccessible due to floodwaters or if there is a loss
of electricity.

* The City of Galveston has issued a voluntary evacuation for
the West End of the city and for low-lying areas beginning at
10 AM today in anticipation of flooding from elevated tides
and flooding rains.

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.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

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