SITUATION OVERVIEW
------------------
Potential Tropical Cyclone One continues to move northwestward
through the southwest Gulf of Mexico. It may develop into a Tropical
Storm over the next 12 to 18 hours before making landfall in eastern
Mexico late Wednesday night or early Thursday morning. Despite it
making landfall in Mexico and regardless of development, it has a large
wind field that will bring hazardous marine and coastal conditions to
Southeast Texas. Starting at San Luis Pass, Tropical Storm Warnings are
in effect for the coast southwards. Occasional strong wind gusts will
be possible for the rest of the the southeast Texas coast, so a Wind
Advisory is also in effect from San Luis Pass to High Island. Strong
winds will also be felt over the coastal waters where wind gusts up to
50 knots will be possible causing seas to rise to near 18 feet.
Coastal Flood Warnings are in effect along the coast as well where up
to 2 to 4 feet of innundation is possible. Water may wash over low-
lying roadways with some beach access becoming impassable. Locally
heavy rainfall will be possible tonight through Wednesday afternoon
mainly for areas south of I-10. Minor urban and small stream flooding
is likely with a few instances of flash flooding possible. Winds will
slowly decrease through the day on Thursday, but elevated tides will
continue to be possible through Friday.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible significant
impacts across the southeast Texas coast. 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.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across areas south of the I-10 corridor. Potential
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.
Protect against dangerous rainfall flooding having possible limited
to significant impacts across the rest of southeast Texas.
* WIND:
Protect against hazardous wind having possible limited impacts across
the southeast Texas coast. 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 Southeast Texas, little to no impact is anticipated.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Follow the advice of local officials.
* 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.
Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.
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
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.
Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!
Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
