SITUATION OVERVIEW
------------------
Advisories have been initiated for Potential Tropical Cyclone 3.
This disturbance is expected to become a tropical depression or
tropical storm by Friday morning. If it becomes a tropical storm it
will be named Claudette. This system is expected to approach the
coast late Friday night with impacts expected to begin during the
day Friday and persist well into Saturday. The main concern is
locally heavy rain leading to flash flooding mainly late Friday
afternoon through Saturday.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts mainly along and east of I-55. Potential
impacts include:
- Moderate rainfall flooding may prompt several evacuations and
rescues.
- Rivers and tributaries may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots. Small streams, creeks, canals, and
ditches overflow.
- Flood waters can enter some structures or weaken foundations.
Several places may experience expanded areas of rapid
inundation at underpasses, low-lying spots, and poor drainage
areas. Some streets and parking lots take on moving water as
storm drains and retention ponds overflow. Driving conditions
become hazardous. Some road and bridge closures.
Protect against locally hazardous rainfall flooding having possible
limited impacts across west of I-55.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast Louisiana and South Mississippi. 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
Southeast Louisiana and South Mississippi. Potential impacts 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.
* SURGE:
Protect against locally hazardous surge having possible limited
impacts across the immediate 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 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.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Listen to local official for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.
* OTHER PREPAREDNESS INFORMATION:
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!
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.
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.
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.
