        <description>* LOCATIONS AFFECTED
- Norco
- Des Allemands
- Boutte

* WIND
- LATEST LOCAL FORECAST: Below tropical storm force wind
- Peak Wind Forecast: 10-20 mph with gusts to 30 mph

- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 39
to 57 mph
- The wind threat has remained nearly steady from the
previous assessment.
- PLAN: Plan for hazardous wind of equivalent tropical storm
force.
- PREPARE: Remaining efforts to protect property should be
completed as soon as possible. Prepare for limited wind
damage.
- ACT: Move to safe shelter before the wind becomes hazardous.

- POTENTIAL IMPACTS: Limited
- 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.

* STORM SURGE
- LATEST LOCAL FORECAST: Life-threatening storm surge possible
- Peak Storm Surge Inundation: The potential for 2-4 feet
above ground somewhere within surge prone areas
- Window of concern: through Thursday afternoon

- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm
surge flooding greater than 3 feet above ground
- The storm surge threat has remained nearly steady from the
previous assessment.
- PLAN: Plan for life-threatening storm surge flooding of
greater than 3 feet above ground.
- PREPARE: Evacuation efforts and flood preparations should
soon be brought to completion before conditions become
unsafe.
- ACT: Leave immediately if evacuation orders are given for
your area to avoid being cut off from emergency services or
needlessly risk lives.

- POTENTIAL IMPACTS: Significant
- Areas of inundation from storm surge flooding. 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. 3 to 6 feet of inundation is possible
outside the hurricane protection levee on the east bank and
for most of the west bank except for areas near the
Mississippi River levee. No inundation expected inside the
hurricane protection levee on the east bank of the
Mississippi River.
- Major shoreline erosion with heavy surf. Strong and
numerous rip currents.
- Moderate damage to marinas, docks, boardwalks, and piers.
Several small craft broken away from moorings, especially
in unprotected anchorages.

* FLOODING RAIN
- LATEST LOCAL FORECAST:
- Peak Rainfall Amounts: Additional 1-3 inches, with locally
higher amounts

- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for
moderate flooding rain
- The flooding rain threat has increased from the previous
assessment.
- PLAN: Emergency plans should include the potential for
moderate flooding from heavy rain. Evacuations and rescues
are possible.
- PREPARE: Consider protective actions if you are in an area
vulnerable to flooding.
- ACT: Heed any flood watches and warnings. Failure to take
action may result in serious injury or loss of life.

- POTENTIAL IMPACTS: Significant
- 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, bayous, 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.

* TORNADO
- LATEST LOCAL FORECAST:
- Situation is somewhat favorable for tornadoes

- THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for a few
tornadoes
- The tornado threat has remained nearly steady from the
previous assessment.
- PLAN: Emergency plans should include the potential for a
few tornadoes.
- PREPARE: If your shelter is particularly vulnerable to
tornadoes, prepare to relocate to safe shelter before
hazardous weather arrives.
- ACT: If a tornado warning is issued, be ready to shelter
quickly.

- POTENTIAL IMPACTS: Limited
- 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.
