THE NATIONAL WEATHER SERVICE IN MOBILE AL HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL 100 PM CDT
FOR PEOPLE IN THE FOLLOWING LOCATION...

IN NORTHWESTERN FLORIDA

   ...OKALOOSA
 
SEVERAL REPORTS OF MINOR FLOODING HAVE BE RECEIVED FROM OKALOOSA
COUNTY DURING THE PAST HOUR. MOST OF THE REPORTS ARE FROM THE
SOUTHERN PART OF THE COUNTY WHERE SEVERAL INCHES OF WATER HAS FLOODED
THE OKALOOSA ISLAND FIRE DEPARTMENT AS WELL AS PARTS OF THE
EMERGENCY OPERATIONS CENTER IN FORT WALTON. WHILE THE RAIN HAS
TEMPORARILY ENDED IN THAT AREA...MORE HEAVY RAIN WILL MOVE EAST
ACROSS THE REGION THROUGH 1 PM.

WATER HAS ALSO BEEN REPORTED ACROSS A BRIDGE ON OLD ANTIOCH ROAD NEAR
CRESTVIEW. WITH ADDITIONAL RAIN ALREADY MOVING INTO THE CRESTVIEW
AREA FROM THE WEST...THIS FLOODING WILL LIKELY CONTINUE.
 
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 FLOODING OCCUR IN AUTOMOBILES.
