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

OVERVIEW...At 730 PM CDT, Tropical Storm Gordon was centered near
29.8 North, longitude 87.9 West. The system is moving toward the
north-northwest near 20 mph, and this general motion is expected
to continue until landfall occurs tonight along the north-central
Gulf Coast. A northwestward motion with some decrease in forward
speed is expected after landfall, with a gradual turn toward the
north-northwest and north forecast to occur on Friday. On the
forecast track, the center of Gordon will approach the north-
central Gulf Coast within the Hurricane Warning area late this
afternoon or evening and move inland over the lower Mississippi
Valley on Wednesday.

The primary impact will be significant tropical storm force winds
across portions of southeast Louisiana and the Mississippi coast
tonight, with hurricane conditions possible in the Hurricane
Warning area tonight. Wind gusts in excess of 50 mph have been
reported from Dauphin Island Alabama within the last hour.

Secondary threats are heavy rainfall of 4 to 6 inches with
locally higher amounts along the Mississippi coast, with up to 3
inches elsewhere, Storm surge of 3 to 5 feet is expected along
the Mississippi coast, and 2 to 4 feet of surge is expected along
east facing shorelines to 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 remaining portions of southeast Louisiana and southern
Mississippi east of Interstate 55.

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

* SURGE:
Protect against life-threatening surge having possible significant
impacts across the Mississippi coastal counties. 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 the southeast Louisiana coastline east of 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 the Mississippi coastal counties. 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 areas east of a Liberty Mississippi to LaPlace
to Grand Isle line.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across the Mississippi coast. 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
----------------------------------

* OTHER PREPAREDNESS INFORMATION:
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 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.

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.
