POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Potential impacts from the flooding rain are still possible across
much of southeast Louisiana and southern Mississippi. Remain well
guarded against life-threatening flood waters having possible
extensive impacts. If realized, these 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.
* TORNADOES:
Potential impacts from tornadoes are still unfolding across Southeast
Louisiana and South Mississippi. Remain well braced against a tornado
event having possible limited impacts. If
realized, these 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.
* SURGE:
Impacts from the main surge event are beginning to recede across
coastal portions of southeast Louisiana and Mississippi. Remain well
away from any life-threatening surge having possible significant
impacts. If realized, these impacts 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.
* WIND:
Potential impacts from the main wind event are lessening across
southeast Louisiana and southern Mississippi. Remain well sheltered
from hazardous wind having possible limited impacts. If realized,
these 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Do not enter evacuated areas until officials have given the all
clear to return.

safest place within your shelter. Protect your head and body.
