FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE MOBILE AL
133 AM CST SUN MAR 8 1998


THE NATIONAL WEATHER SERVICE IN MOBILE AL HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL 330 AM CST
FOR PEOPLE IN THE FOLLOWING LOCATION...

IN SOUTHERN ALABAMA

   ...COVINGTON COUNTY

THE GROUND OVER THE AREA REMAINS SATURATED FROM RECENT RAINFALL OVER
COVINGTON COUNTY...AND ADDITIONAL HEAVY RAINFALL WHICH DEVELOPED OVER
THE AREA SINCE 10 PM HAS PRODUCED SOME FLASH FLOODING. HEAVY
RAINFALL WILL CONTINUE TO MOVE EAST ACROSS THE COUNTY THROUGH 330 AM.
DOPPLER WEATHER RADAR PRECIPITATION ESTIMATES INDICATE THAT 2 TO 4
INCHES OF ADDITIONAL RAINFALL WILL OCCUR THROUGH 330 AM.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE
DANGERS OF FLOODS AND FLASH FLOODS. IF FLASH FLOODING IS OBSERVED...
ACT QUICKLY. MOVE UP TO ESCAPE FLOOD WATERS. DO NOT STAY IN AREAS
SUBJECT TO FLOODING WHEN WATER BEGINS RISING. IT IS VERY DIFFICULT
AT NIGHT TO TELL HOW MUCH WATER IS ON ROADS. MOTORISTS SHOULD NOT
DRIVE THROUGH WATER OF UNKNOWN DEPTH.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY AND THE ROAD BENEATH MAY NOT BE INTACT. VEHICLES
CAUGHT IN RISING WATER SHOULD BE ABANDONED QUICKLY. IT ONLY TAKES
A FOOT OR TWO OF FLOWING WATER TO WASH MOST CARS AWAY. REMEMBER...
MOST DEATHS IN FLASH FLOODPING OCCUR IN AUTOMOBILES.
