DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Storm Gordon was
located by NOAA Doppler weather radars near latitude 29.4 North,
longitude 87.8 West. Gordon is moving toward the northwest near 15
mph (24 km/h) 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 make landfall along the north-central Gulf Coast
within the hurricane warning area this evening or tonight, and then
move inland over the lower Mississippi Valley through Wednesday.

Data from NOAA Doppler weather radars indicate that maximum
sustained winds have increased to near 70 mph (110 km/h) with
higher gusts. Some additional strengthening is still possible, and
Gordon could become a hurricane before landfall occurs along the
north-central Gulf Coast this evening. Rapid weakening is forecast
after Gordon moves inland.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.

The estimated minimum central pressure is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Mouth of the Pearl River to Dauphin Island...3 to 5 ft.
Navarre Florida to Dauphin Island, including Mobile Bay...2 to 4 ft.
Mouth of the Pearl River to the Mouth of Mississippi River...2 to 4
ft.

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your area,
please see products issued by your local National Weather Service
forecast office.

RAINFALL:  Gordon is expected to produce total rain accumulations of
4 to 8 inches over the western Florida Panhandle, southwest Alabama,
southern and central Mississippi, northeastern Louisiana, and
southern Arkansas, with isolated maximum amounts of 12 inches
through late Thursday. This rainfall will cause flash flooding
across portions of these areas.

WIND:  Tropical storm conditions will spread onshore within portions
of the warning area during the next few hours, with hurricane
conditions expected by this evening in the hurricane warning area.

TORNADOES:  A couple of tornadoes are possible through tonight
near the coasts of Mississippi, Alabama, and the Florida Panhandle.
