1200 PM EDT TUE SEP 29 1998

...FLASH FLOOD WATCH IN EFFECT THROUGH WEDNESDAY...
...TORNADO WATCH IN EFFECT UNTIL 8 PM EDT (7 PM CDT)...
...SMALL CRAFT SHOULD REMAIN IN PORT UNTIL WINDS AND SEAS
SUBSIDE...

AT 11 AM EDT...TROPICAL DEPRESSION GEORGES WAS LOCATED 35 MILES NORTH
NORTHEAST OF MOBILE ALABAMA.  THE DEPRESSION IS EXPECTED TO WEAKEN
AS IT MOVES SLOWLY TO THE EAST NORTHEAST DURING THE NEXT 24 HOURS.
THE DEPRESSION WILL CONTINUE TO PULL ABUNDANT TROPICAL MOISTURE
NORTHWARD INTO THE REGION THROUGH WEDNESDAY. NUMEROUS SHOWERS AND
THUNDERSTORMS WITH VERY HEAVY RAIN WILL CONTINUE TO OVERSPREAD THE
REGION AND WILL LIKELY PRODUCE FLOODING. RAINFALL TOTALS DURING THE
NEXT 24 HOURS MAY EXCEED 6 TO 8 INCHES OVER PORTIONS OF SOUTHEAST
ALABAMA...SOUTHWEST GEORGIA AND THE PANHANDLE...WITH 3 TO 5 INCHES
POSSIBLE OVER THE BIG BEND. SOME OF THE THUNDERSTORMS MAY PRODUCE
STRONG GUSTY WINDS AND ISOLATED TORNADOES THIS AFTERNOON AND
EVENING.

IN ADDITION TO THE SEVERE WEATHER THREAT...THE POTENTIAL FOR
COASTAL FLOODING WILL INCREASE TONIGHT ALONG SOUTH AND SOUTHWEST
FACING COASTLINES (ST MARKS TO THE SUWANNEE RIVER).  SUSTAINED
SOUTH WINDS OF 15 TO 25 MPH WITH HIGHER GUSTS TODAY AND TONIGHT
WILL BECOME MORE SOUTHWESTERLY WEDNESDAY AS THE DEPRESSION MOVES INTO
GEORGIA.  THIS MAY GENERATE STORM SURGES OF 2 TO 3 FEET ABOVE
NORMAL TIDAL LEVELS TONIGHT AND WEDNESDAY MORNING RESULTING IN
MINOR BEACH EROSION.  A COASTAL FLOOD WATCH MAY BE ISSUED LATER
TODAY.

SPOTTER ACTIVATION IS REQUESTED THIS AFTERNOON AND TONIGHT.
