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

At 400AM CDT, Tropical Storm Nate is moving toward the north-northwest
near 14 mph and is expected to continue on this general heading through
Friday and then speeding up over the Gulf. Maximum sustained winds
are now 45 mph. Hurricane and Storm Surge watches have now been issued for
much of the area.

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

* SURGE:
Prepare for life-threatening surge having possible extensive impacts
across coastal Louisiana and coastal Mississippi, outside of the hurricane
protection levee 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:
Prepare for life-threatening wind having possible extensive impacts
across much of 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.

* FLOODING RAIN:
Prepare for 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.

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

* EVACUATIONS:

WATCH 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 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 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 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.

WATCH 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 check your emergency plan and take necessary
actions to secure your home or business. Deliberate efforts should be
underway to protect life and property. Ensure that your Emergency
Supplies Kit is stocked and ready.

When making safety and preparedness decisions, do not focus on the
exact forecast track as there are inherent forecast uncertainties
which must be taken into account.

If you live in a place that is particularly vulnerable to high wind,
such as a mobile home, an upper floor of a high rise building, or on
a boat, plan to move to safe shelter. Take enough supplies for you
and your family for several days.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low lying or poor
drainage area,or near an already swollen river, plan to move to safe
shelter on higher ground

Always heed the advice of local officials and comply with any orders
that are issued. Do not needlessly jeopardize your life or the lives
of others.

When securing your property, outside preparations should be conducted
as soon as possible before conditions deteriorate. The onset of
strong gusty winds and heavy rain can cause certain preparedness
activities to become unsafe.

Be sure to let friends and other family members know of your
intentions and whereabouts for surviving the storm. For emergency
purposes, have someone located away from the threatened area serve as
your point of contact. Share vital contact information with others.
Keep cell phones handy and well charged.

Be a Good Samaritan and check on those who may not be fully aware of
the situation or who are unable to make personal preparations.

Visitors to the area should become familiar with nearby surroundings.
If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.

Closely monitor NOAA Weather Radio or other local news outlets for
official storm information. Listen for possible changes to the
forecast.
