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

OVERVIEW...At 400 AM CDT, the center of Tropical Storm Gordon was
located near latitude 27.7 North, longitude 85.7 West. Gordon is
moving toward the west-northwest near 17 mph.   A west-northwestward
to northwestward motion with some decrease in forward speed is
expected over the next few days.  On the forecast track, the center
of Gordon will move across the eastern Gulf of Mexico today, and
will approach the north-central Gulf Coast within the warning area
late this afternoon or evening, and move inland over the lower
Mississippi Valley tonight or early Wednesday.

The primary impact will be significant tropical storm force winds
across portions of southeast Louisiana and the Mississippi coast by
late this afternoon, with hurricane conditions expected in the Hurricane
Warning area tonight. Secondary threats are heavy rainfall of 4 to 7
inches with locally higher amounts, and storm surge of 3 to 5 feet,
primarily along the Mississippi coast and Lake Borgne, 2 to 4 feet
of surge is expected to the mouth of the Mississippi River and 1
to 2 feet along the Louisiana coast to the west of the mouth of
the Mississippi River.

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

* WIND:
Protect against dangerous wind having possible significant impacts
across coastal Mississippi. 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 portions of Southeast Louisiana and Southern Mississippi mainly
to the east of a McComb to Slidell line.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across the Mississippi coast and along the Louisiana coast
from Shell Beach to the Mississippi state line. 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 across coastal Louisiana extending from Shell Beach to the mouth
of the Mississippi River.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across portions of southern Mississippi and
southeast Louisiana mainly east of a McComb to Slidell line. 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, 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.

Protect against locally hazardous rainfall flooding having possible
limited impacts across the remainder of Southeast Louisiana and
Southern Mississippi.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of southern Mississippi and southeast Louisiana
mainly east of a McComb to Slidell line. 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:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

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.

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

* 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.

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.

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.
