NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED NUMEROUS SHOWERS AND
THUNDERSTORMS STEADILY PROGRESSING INLAND FROM THE GULF OF MEXICO.

HOURS.
 
TORRENTIAL RAINS WHICH HAVE ALREADY FALLEN ACROSS THE AREA...COMBINED
WITH ADDITIONAL HEAVY RAIN EXPECTED TO MOVE INLAND FROM THE GULF OF
MEXICO PRIOR TO SUNRISE HAS MADE THE POTENTIAL FOR FLASH FLOODING VERY
LIKELY.

IMMINENT. MOST FLASH FLOOD DEATHS OCCUR IN AUTOMOBILES. DO NOT
ATTEMPT TO CROSS BRIDGES...DIPS...OR LOW SPOTS IF WATER COVERS
