SITUATION OVERVIEW
------------------

...OVERVIEW...At 10 AM CDT, Hurricane Nate is moving toward
the north- northwest near 26 mph as a strong Category 1 hurricane
with 90 mph winds, and is expected to continue on this
general heading through this afternoon and evening.  Hurricane Nate
is expected to make landfall tonight somewhere along the Mississippi
Coast as a Category 2 hurricane.  The main impacts across southeast
Louisiana and southern Mississippi will be damaging winds and storm
surge flooding along the immediate coast and tidal locations.

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

* SURGE:
Protect against life-threatening surge having possible devastating
impacts across the immediate Mississippi coast and across parts of
Southeast Louisiana east of the Mississippi River outside of the
hurricane risk reduction levee system including portions of
Plaquemines, St. Bernard, Orleans, and far Southeastern St. Tammany
Parishes. Potential impacts in this area include:
    - Widespread deep inundation, with storm surge flooding greatly
      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.

Also, protect against life-threatening surge having possible
significant to extensive impacts across the immediate shoreline of
Lake Pontchartrain and along the Southeast Louisiana coast west of the
Mississippi River.

* WIND:
Protect against life-threatening wind having possible extensive
impacts across Mississippi coastal counties of Jackson, Harrison,
and Hancock as well as portions of extreme Southeast Louisiana
including much of Lower Plaquemines and Lower St. Bernard
Parishes. Potential impacts in this area 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.

Also, protect against dangerous wind having possible limited to
significant impacts across inland areas of southern Mississippi
mainly east of the Interstate 55 corridor including Pearl River County
and parishes east of Interstate 55 corridor in Southeast Louisiana
including metro New Orleans.

* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across Southeast Louisiana and South Mississippi.
Potential impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, bayous, and ditches may become
      swollen and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across the Mississippi coastal counties and extreme Southeast
Louisiana including lower Plaquemines and Lower St. Bernard Parishes.
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.

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

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

* EVACUATIONS:
WATCH/WARNING PHASE - For those under evacuation orders, leave as
soon as practical with a destination in mind. Gas up your vehicle
well ahead of time. Be sure that you take all essential materials
from your emergency supplies kit. Let others know where you are going
and when you intend to arrive.

WATCH/WARNING PHASE - If evacuating the area, stick to prescribed
evacuation routes. Look for additional traffic information on roadway
smart signs and listen to select radio channels for further travel
instructions. Drivers should not use cell phones while operating
vehicles.

WATCH/WARNING PHASE - For those not under evacuation orders,
understand that there are inherent risks to evacuation (such as
traffic congestion, accidents, and driving in bad weather), so
evacuate only if necessary. Help keep roadways open for those that
are under evacuation orders.

WATCH/WARNING PHASE - If evacuating away from the area or relocating
to a nearby shelter, leave early before weather conditions become
hazardous.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.

Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.

If you are relocating to safe shelter, leave as early as possible. If
heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or own a
pet. Take essential items with you from your Emergency Supplies Kit.
Check the latest weather forecast before departing.

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.

Check-in with your emergency points of contact among family, friends,
and workmates. Inform them of your status and well-being. Let them
know how you intend to ride out the storm and when you plan to
check-in again.

Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.

In emergencies it is best to remain calm. Stay informed and focused
on the situation at hand. Exercise patience with those you encounter.
Be a Good Samaritan and helpful to others.

If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.

Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
