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

OVERVIEW...At 730 AM CDT, the center of Tropical Storm Gordon was
located by NOAA Doppler weather radar and surface observations
near latitude 25.1 North, longitude 80.7 West. Gordon is moving
toward the west-northwest near 17 mph and a west-
northwestward to northwestward motion is expected through Wednesday.
On the forecast track, the center of Gordon will pass
over the southern tip of the Florida peninsula this morning, move
over the southeastern Gulf of Mexico this afternoon and evening, and
reach the warning area along the central Gulf Coast by late Tuesday
or Tuesday night.

The primary impact will be heavy rainfall that could produce inland
flooding. Rainfall should range 4 to 7 inches across coastal
Mississippi and southeast Louisiana with locally higher amounts
possible. Secondary impacts across coastal Mississippi and southeast
Louisiana will be tropical storm force winds and storm surge of 2 to
4 feet above ground level east of the Mississippi River excluding Lake
Pontchartrain.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across portions of Southeast Louisiana mainly north
of Interstate 10 and Southwest Mississippi mainly west of Interstate 55.
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, Southwest
Mississippi, and Coastal Mississippi.

* WIND:
Protect against dangerous wind having possible significant impacts
across all of Coastal and Southwest Mississippi, and across portions
of Southeast Louisiana mainly north and east of a Baton Rouge to New
Orleans line.
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 mainly south and west of a
Baton Rouge to New Orleans line.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across Coastal Mississippi and Coastal Louisiana east of the
mouth of the Mississippi River excluding Lake Pontchartrain and Maurepas.
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 along the shores of Lake Pontchartrain and Maurepas.

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

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

* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

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, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
