SITUATION OVERVIEW
------------------
Tropical Depression Two is currently south off the coast of the
Florida Peninsula and will gradually strengthen as it moves northwest.
Two is forecast to bring the threat of tropical storm force wind gusts,
locally heavy rainfall south of I-10, and storm surge. The coastal
areas of Mississippi and southeast Louisiana will have the greatest
threat, especially south of I-10.
Tropical storm watches have been issued for the Mississippi coast and
southeast Louisiana east of the mouth of the Mississippi River. A
tropical storm watch has been issued for the coastal waters, sounds
east of the mouth of the Mississippi as well as for Lake Borgne.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts south of I-10, especially near the coast. 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.
Prepare for locally hazardous rainfall flooding having possible
limited impacts across coastal Mississippi and elsewhere in southeast
Louisiana along the I-10/I-12 corridor.
* WIND:
Prepare for hazardous wind having possible limited impacts across the Louisiana and
Mississippi coasts. 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 Louisiana and South Mississippi, little to
no impact is anticipated.
* SURGE:
Prepare for life-threatening surge having possible significant
impacts across the Louisiana coast east of the mouth of the Mississippi
River and coastal Mississippi. 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.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* TORNADOES:
Little to no tornado impacts are anticipated at this time
across Southeast Louisiana and South Mississippi.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* OTHER PREPAREDNESS INFORMATION:
When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.
Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.
If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.
Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
