SITUATION OVERVIEW
------------------
At 8 PM CDT, a large area of low pressure in the Bay of Campeche
continues to remain unorganized and move north at 6 mph. This system
is expected to slowly strengthen and begin to move more westward
tonight into tomorrow and expected approach the central Mexico Gulf
coast tomorrow evening as a Tropical Storm. Tropical Storm Warnings
remain in effect for coastal waters, barrier islands and coastal
portions of Kenedy, Willacy and Cameron counties.
The main hazard across the lower Texas coast into Deep South Texas
remains flooding rainfall of generally 4-8 inches, with localized
rainfall amounts up to 10 or more inches, especially towards the
coast. Beach and marine conditions are becoming dangerous as well,
with coastal flooding of up to 3 feet likely, deadly rip currents,
high surf, gusty winds, and low visibility in heavy rainfall. The
strongest winds of this tropical system may reside well north of any
circulation. Tropical wind gusts up to 50 mph are likely offshore
and potentially into coastal portions of Kenedy, Willacy, and
Cameron counties. Higher winds gusts are also possible inland with
bands of showers and thunderstorms.
POTENTIAL IMPACTS
-----------------
* TORNADOES:
Protect against a tornado event having possible limited impacts
across The Rio Grande Valley and Deep 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:
Protect against hazardous wind having possible limited impacts across
the lower Texas coast and coastal portions of Kenedy, Willacy, and
Cameron counties. 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 The Rio Grande Valley and Deep South Texas, little
to no impact is anticipated.
* SURGE:
Protect against locally hazardous surge having possible limited
impacts across the lower 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 exposed parking lots could
become covered with some 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 damage to marinas, docks, boardwalks, and piers. A few
small craft broken away from moorings.
Elsewhere across The Rio Grande Valley and Deep South Texas, little
to no impact is anticipated.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across The Rio Grande Valley and Deep South Texas.
Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Small streams, creeks, canals, arroyos, 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 filled with several feet of
water with underpasses submerged. Driving conditions become
dangerous. Many road and bridge closures with some weakened or
washed out.
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.
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 in which it resides.
Listen for these locations in local news updates. Pay attention for
instructions from local authorities.
Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the 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.
