FLOOD WARNING
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
740 AM EDT SAT MAY 11 1996

THE NATIONAL WEATHER SERVICE IN GRAND RAPIDS HAS ISSUED A
FLOOD WARNING EFFECTIVE UNTIL  400 PM EDT
FOR PEOPLE IN THE FOLLOWING LOCATIONS...

IN SOUTHWEST LOWER MICHIGAN

   ...SOUTH HALF OF BERRIEN COUNTY...

THE FLOOD WARNING FOR THE SOUTH HALF OF BERRIEN COUNTY HAS BEEN
EXTENDED UNTIL 400 PM THIS AFTERNOON. LOCAL AUTHORITIES CONTINUE
TO REPORT FLOOD RELATED PROBLEMS ESPECIALLY IN THE SOUTHWEST CORNER
OF BERRIEN COUNTY AROUND GALIEN. RECENT HEAVY RAIN HAS CAUSED NUMEROUS
ROADS TO WASH OUT. WATER STILL COVERS THE AREA AROUND 12TH AND
CLEVELAND IN DOWNTOWN GALIEN.

AT 735 AM EDT... NATIONAL WEATHER SERVICE DOPPLER RADAR DID NOT
DETECT ANY PRECIPITATION IN SOUTHWEST LOWER MICHIGAN AND NO
PRECIPITATION IS EXPECTED TODAY.  HOWEVER... ALTHOUGH THE THREAT OF
HEAVY RAIN HAS ENDED... THE WATER LEVELS OF MANY RIVERS AND CREEKS
REMAIN HIGH. PONDING OF WATER IN LOW AREAS IS ALSO CAUSING ROADS TO
BE IMPASSABLE.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROAD. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOU TO CROSS SAFELY.
DARKNESS ONLY SERVES TO CONCEAL THIS DANGER. IF FLOOD WATERS
THREATEN YOUR LOCATION PLAN ALTERNATIVE TRAVEL ROUTES IF POSSIBLE.
