SITUATION OVERVIEW
------------------
Tropical Storm Francine is forecast to move north-northeast
overnight with rapid weakening expected as it moves away from
Southeast Louisiana and Southern Mississippi. Tropical Storm Warnings
and Storm Surge Warnings remain in place.
POTENTIAL IMPACTS
-----------------
* WIND:
Potential impacts from the main wind event are now unfolding across
Southeast Louisiana and South Mississippi. Remain well sheltered from
life-threatening wind having possible extensive impacts. If realized,
these impacts 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, causeways, and
access routes impassable.
- Large areas with power and communications outages.
* SURGE:
Potential impacts from the main surge event are now unfolding across
coastal Southeast Louisiana and Southern Mississippi Remain well away
from life-threatening surge having potential extensive impacts. If
realized, these impacts include:
- Large areas of deep inundation with storm surge flooding
accentuated by battering waves. Structural damage to buildings,
with several washing away. Damage compounded by floating
debris. Locations may be uninhabitable for an extended period.
- Large sections of near-shore escape routes and secondary roads
washed out or severely flooded. Flood control systems and
barriers may become stressed.
- Severe beach erosion with significant dune loss.
- Major damage to marinas, docks, boardwalks, and piers. Many
small craft broken away from moorings, especially in
unprotected anchorages with some lifted onshore and stranded.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Southeast Louisiana and South 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 coastal Mississippi. Remain well braced against a
dangerous tornado event having possible significant impacts. If
realized, these impacts include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.
Do not venture outside while in the eye of a hurricane as any
improvement in weather will only be temporary. Once the eye passes,
conditions will become life threatening as winds immediately return
to dangerous speeds, so remain safely sheltered from the storm.
Do not be a thrill seeker or risk your life for senseless photos or
videos.
If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.
If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.

SITUATION OVERVIEW
------------------
Hurricane Francine is approaching the Louisiana coast and is expected
to make landfall later this evening.
Hurricane and Tropical Storm Warnings remain active across Southeast
Louisiana and Southern Mississippi. In addition to the potential for
damaging winds, Francine will also bring the threat of life-
threatening storm surge along the coastline and lakeshores of
Southeast Louisiana and Southern Mississippi where Storm Surge
Warnings are currently in place. Heavy rainfall along and to the east
of the track will have the potential to cause flooding and flash
flooding even in areas that don't normally flood. Rainfall flooding
could be worsened due to the heavy rainfall that saturated grounds
just last week.
POTENTIAL IMPACTS
-----------------
* SURGE:
Potential impacts from the main surge event are now unfolding across coastal
southeast Louisiana and south Mississippi. Remain well away from life-threatening
surge having potential devastating impacts. If realized, these impacts

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.
- Near-shore escape routes and secondary roads washed out or
severely flooded. Flood control systems and barriers may become
stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers.
Numerous small craft broken away from moorings with many lifted
onshore and stranded.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Southeast Louisiana and South 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

Potential impacts from tornadoes are still unfolding across southeast
Louisiana and south Mississippi. Remain well braced against a dangerous
tornado event having possible significant impacts. If
