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

...OVERVIEW...At 1030 PM CDT, Nate was classified as a Hurricane and
is moving toward the north-northwest near 22 mph and is expected to
continue on this general heading through Saturday night into early
Sunday. The main impacts across southeast Louisiana and south
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 extensive
impacts across coastal and tidal locations in both Southeast
Louisiana and Mississippi including the shores of Lake Pontchartrain
outside of the hurricane risk reduction system.

Potential impacts in this area 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.

* WIND:
Protect against life-threatening wind having possible extensive
impacts across extreme Southeast Louisiana and coastal Mississippi.

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 portions of Southeast Louisiana mainly
along and east of the Interstate 55 corridor including metro New
Orleans...River Parishes...and Bayou Region near Houma.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across coastal Mississippi and portions of
Southeast Louisiana mainly east of the Interstate 55 corridor.

Potential impacts include:
    - 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.

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

* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of extreme Southeast Louisiana and coastal
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.

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

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

* EVACUATIONS:
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.

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 you are exceptionally vulnerable to wind or
water hazards from tropical systems, consider voluntary evacuation,
especially if being officially recommended. Relocate to a
predetermined shelter or safe destination.

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.

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.

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.
