DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the center of Tropical Storm Gordon was
located near latitude 30.3 North, longitude 88.4 West. Gordon is
moving toward the northwest near 14 mph (22 km/h). A
northwestward motion with some decrease in forward speed is
expected over the next couple of days. On the forecast track, the
center of Gordon will move inland across the lower Mississippi
Valley through Wednesday. A turn toward the north-northwest
and north is forecast to occur on Friday.
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Rapid weakening is forecast after Gordon moves inland, and
Gordon is forecast to become a tropical depression on Wednesday.
Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center. A NOAA Coastal Marine Observing site on Dauphin
Island, Alabama has measured a sustained wind of 57 mph (91 km/h)
with a gust to 72 mph (117 km/h). A wind gust of 61 mph (98 km/h)
was recently observed at the Pensacola Naval Air Station.
The latest minimum central pressure estimated from NOAA Hurricane
Hunter aircraft data is 997 mb (29.44 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 Mississippi River to Biloxi...1 to 3 ft.
Biloxi to the Alabama/Florida Border including Mobile Bay...2 to
4 ft.
Alabama/Florida Border to Navarre, Florida...1 to 3 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 and hurricane conditions will continue to
spread onshore during the next several hours within portions of the
warning area.
TORNADOES: A couple of tornadoes are possible tonight near the
coasts of Alabama and the western Florida Panhandle.
Here's the projected track of Gordon over the next few days:
