SITUATION OVERVIEW
------------------
Hurricane Delta is now moving to the north over the west
central Gulf of Mexico. The storm has maintained its strength as a category
three hurricane this morning with sustained winds near 120 mph.
Delta is currently located approximately 200 miles south of Cameron.
A turn to the north northeast is expected by this evening along with a
gradual weakening trend as Delta approaches the coastline. Regardless of
any weakening trend, Hurricane Delta is expected to be a large and very
dangerous storm. Landfall is expected Friday evening along the
Cameron Parish coastline. Tropical storm force winds are expected to
begin near the coast Friday morning, with conditions continuing to
deteriorate thereafter. Life threatening storm surge is expected in
vulnerable coastal areas. Dangerous hurricane force winds are expected
in portions of southwest, south central, and central Louisiana, with
tropical storm force winds elsewhere. Rainfall of 4 to 10 inches with
locally higher amounts will be possible, with the highest amounts
expected near the center of cirulation. As such flash flooding will be
an additional threat with Delta.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible devastating
impacts across coastal southwest and south central 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.
Also, protect against life-threatening surge having possible
significant to extensive impacts across coastal southwest Louisiana.
Also, protect against locally hazardous surge having possible limited
impacts across coastal southeast Texas.
Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.
* WIND:
Protect against life-threatening wind having possible extensive
impacts across southwest, south central, and central Louisiana. Potential impacts in
this area include:
- 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 and access routes
impassable.
- Large areas with power and communications outages.
Also, protect against dangerous wind having possible limited to
significant impacts across portions of central and south central Louisiana as well as southeast Texas.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across southwest and central Louisiana. Potential
impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
rescues.
- Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, and ditches may become raging rivers. Flood control
systems and barriers may become stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.
Protect against life-threatening rainfall flooding having possible
significant to extensive impacts across southeast Texas.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across south central Louisiana. 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.
Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.
WATCH/WARNING PHASE - 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.
WATCH/WARNING PHASE - 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.
WATCH/WARNING PHASE - Let others know where you are going prior to
departure. Secure loose items and pets in the car, and avoid
distracted driving.
WATCH/WARNING PHASE - 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.
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.
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 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.
