SITUATION OVERVIEW
------------------
At 10 PM CDT the center of Hurricane Laura was located near latitude 25.2 North,
longitude 89.5W West. Laura is moving toward the west-northwest near
17 mph, and this general motion should continue tonight. A turn toward
the northwest is forecast Wednesday, and a northwestward to
north-northwestward motion should continue through Wednesday night. On
the forecast track, the center of Laura will move across the central
Gulf of Mexico tonight and the northwestern Gulf of Mexico on
Wednesday. The hurricane should approach the Upper Texas and Southwest
Louisiana coasts on Wednesday night and move inland near those areas
late Wednesday night or Thursday morning.
Showers and thunderstorms ahead of the center will begin to overspread
southwest Louisiana and southeast Texas during Wednesday, with an
increasing risk of localized flash flooding. Isolated tornadoes will
also be possible, especially over southwest Louisiana.
Tropical storm force winds are expected to spread across southwest
Louisiana on Wednesday afternoon and southeast Texas by Wednesday
evening. Hurricane force winds, especially in frequent gusts, will be
likely beginning Wednesday night across southwest Louisiana and
southeast Texas continuing into Thursday morning up into upper
southeast Texas and west central Louisiana.
Storm surge of 7 to 14 feet above ground level will be possible along
the coast through Thursday afternoon, along and to the east of where
the center comes ashore. Also a significant surge will occur up the
lower Neches, Sabine, Calcasieu, Mermantau, and Vermilion River
basins.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible devastating
impacts across Southeast Texas and South Louisiana. Potential impacts in
this area include:
- Widespread deep inundation, with storm surge flooding greatly
accentuated by powerful battering waves. Structural damage to
buildings, with many washing away. Damage greatly compounded
from considerable floating debris. Locations may be
uninhabitable for an extended period.
- Escape routes and secondary roads washed out or severely
flooded. Flood control systems and barriers may become stressed
or overtopped.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, and piers. Numerous small
craft broken away from moorings with many lifted onshore and
stranded.
* WIND:
Protect against life-threatening wind having possible devastating
impacts across Southeast Texas and Southwest Louisiana. Potential impacts in
this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges and access routes
impassable.
- Widespread power and communications outages.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across Southeast Texas and Southwest Louisiana. 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
significant impacts across Central and South Central Louisiana.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southwest Louisiana and 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:
Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.
For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location. If
you decide to move, relocate to a safer location nearby. If you do
not relocate, help keep roadways open for those under evacuation
orders.
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.
Let others know where you are going prior to
departure. Secure loose items and pets in the car, and avoid
distracted driving.
If evacuating, follow designated evacuation
routes. Seek traffic information on roadway signs, the radio, and
from official sources.
* 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 relocating to safe shelter, leave as early as possible.
Allow extra time to reach your destination. Many roads and bridges
will be closed once strong winds arrive. Check the latest weather
forecast before departing and drive with caution.
If heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or have
pets. Take essential items with you from your Emergency Supplies Kit.
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.
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.
It is important to remain calm, informed, and focused during an
emergency. Be patient and helpful with those you encounter.
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.
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!
If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.
If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, consider moving to a safer shelter before the onset of
strong winds or flooding.
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.
