POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across all of southeast Louisiana as well as
southwest and coastal Mississippi.

Potential 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.

* WIND:
Protect against dangerous wind having possible significant impacts
across southeast Louisiana and portions of southwest MS. Potential
impacts in this area include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Also, protect against hazardous wind having possible limited impacts
across coastal Mississippi and coastal Louisiana .

* SURGE:
Protect against life-threatening surge having possible significant
impacts across coastal Louisiana and portions of 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.

Also, protect against locally hazardous surge having possible limited
impacts inside the tidal lakes and across the coast of Jackson
county Mississippi.

Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.

* 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATION

WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.

WATCH/WARNING PHASE - For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location. If
you decide to move, relocate to a safer location nearby. If you do
not relocate, help keep roadways open for those under evacuation
orders.

WATCH/WARNING PHASE - If evacuating, leave with a destination in mind
and allow extra time to get there. Take your emergency supplies kit.
Gas up your vehicle ahead of time.

WATCH/WARNING PHASE - Let others know where you are going prior to
departure. Secure loose items and pets in the car, and avoid
distracted driving.

WATCH/WARNING PHASE - If evacuating, follow designated evacuation
routes. Seek traffic information on roadway signs, the radio, and
from official sources.

IMMINENT/ONGOING PHASE - Do not enter evacuated areas until officials
have given the all clear to return.

RECOVERY PHASE - Do not enter evacuated areas until officials have
given the all clear to return.

* OTHER PREPAREDNESS INFORMATION:

Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible.
Allow extra time to reach your destination. Many roads and bridges
will be closed once strong winds arrive. Check the latest weather
forecast before departing and drive with caution.

If heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or have
pets. Take essential items with you from your Emergency Supplies Kit.

Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.

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.

It is important to remain calm, informed, and focused during an
emergency. Be patient and helpful with those you encounter.

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.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.

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!

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.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, consider moving to a safer shelter before the onset of
strong winds or flooding.

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.
