SITUATION OVERVIEW
------------------
Tropical Storm Alberto will continue on a westward track tonight with
landfall expected early tomorrow morning along the coast of Mexico. The
system is very large with tropical-storm-force-winds extending up to
400 miles north of the center.
Across South Texas, Tropical Storm Warnings remain in effect along all
coastal counties, the bays and Gulf waters out to 60 nm from Baffin
Bay through Port O'Connor. In addition, there are several hazards
expected to continue to impact the region through Thursday due to the
large extent and slow movement of the storm. The threats include:
- Flash Flooding: Moderate to high threat of flash flooding through
Thursday. Additional widespread rainfall accumulations of 2-7", with
localized rainfall amounts up to 10".
- Coastal Flooding: Significant coastal flooding is ongoing with peak
inundation of 3 ft possible across the Middle Texas Coast including
the bays between Baffin Bay and Matagorda Bay. Elevated water levels
are expected to linger through Friday. In addition, there is a High
risk of rip currents.
- River Flooding: Limited river flooding is possible on some rivers
across the area, in particular the Nueces River along with Oso Creek
and San Fernando Creek, are a concern. Other rivers could be added to
the list depending on additional overnight rains.
- Winds: Sustained winds of 35 mph with gusts to around 50 mph will be
possible across the Coastal Bend, while winds of up to 40 knots can be
expected over the bays and Gulf waters.
- Tornadoes: Tornadoes and waterspouts will continue to be possible
through Thursday morning within the outer bands of Alberto. There is
currently a tornado watch in effect through 7AM Thursday across all of
South Texas.
- Hazardous Seas: Wave heights 12 to 16 feet.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the Southern Coastal plans and Southern Brush Country. Remain well
guarded against life-threatening flood waters having possible
extensive impacts. If realized, these impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, and ditches may
become dangerous rivers. Flood control systems and barriers may
become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.
Potential impacts from the flooding rain are still unfolding across
the rest of South Texas. Remain well guarded against dangerous
flood waters having possible limited to
significant impacts.
* SURGE:
Protect against locally hazardous surge having possible limited
impacts across the Coastal Bend. 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:
Potential impacts from tornadoes are still unfolding across the Brush Country
and Coastal Bend. Remain well braced against a dangerous tornado
event having possible significant impacts. If realized, these impacts include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.
Potential impacts from tornadoes are still unfolding across the rest of South
Texas. Remain well braced against a tornado event having possible limited impacts.
* WIND:
Protect against hazardous wind having possible limited impacts across
the Coastal Bend. 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Follow the advice of local officials.
