OF HAYS COUNTY...MOVING NORTH AT 15 MPH.  IN ADDITION HEAVY RAIN 
WILL CONTINUE TO FORM OVER THE AREA.

THE WEATHER PATTERN BODES WELL FOR CONTINUED RAIN THE NEXT
FEW HOURS...CAUSING FLOODING AT LOW WATER CROSSINGS...LOW LYING 
AREAS AND OTHER FLOOD PRONE AREAS IN GUADALUPE COUNTY.

VEHICLES IN LOW WATER CROSSINGS.  MOTORISTS SHOULD NOT DRIVE IN 
FLOOD PRONE AREAS.

CREEKS AND STREAMS CAN RISE RAPIDLY... FLOODING ROADS...
HIGHWAYS...AND CAMPS IN LOW LYING AREAS.

EXCESSIVE RUNOFF FROM THESE STORMS WILL CAUSE FLASH FLOODING OF SMALL

ADDITIONALLY...COUNTRY ROADS AND FARMLANDS ALONG THE BANKS OF CREEKS
AND STREAMS AND OTHER LOW LYING AREAS ARE SUBJECT TO FLASH FLOODING.

AGAIN...DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS 
THE ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO 
CROSS SAFELY. VEHICLES CAUGHT IN RISING WATER SHOULD BE ABANDONED 
QUICKLY. MOVE TO HIGHER GROUND.

A FLASH FLOOD WARNING MEANS THAT FLOODING IS OCCURRING OR IS
IMMINENT. MOST FLASH FLOOD DEATHS OCCUR IN AUTOMOBILES. DO NOT
ATTEMPT TO CROSS BRIDGES...DIPS...OR OTHER LOW SPOTS IF WATER COVERS
THE ROADWAY. NEVER TRY TO CROSS A FLOWING STREAM...EVEN A SMALL
ONE...ON FOOT. TO ESCAPE RISING WATER MOVE UP TO HIGHER GROUND.
