FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
628 PM CDT TUE OCT 7 1997
 
THE NATIONAL WEATHER SERVICE IN CORPUS CHRISTI HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL  930 PM CDT
FOR PEOPLE IN THE FOLLOWING COUNTY......
 
IN SOUTH CENTRAL TEXAS
 
   ...SOUTHERN LIVE OAK COUNTY
 
NATIONAL WEATHER SERVICE DOPPLER RADAR ESTIMATED OVER 3 INCHES OF
RAINFALL WITHIN THE PAST HOUR NEAR LAGARTO. THE ADDITIONAL HEAVY
RAINS COMBINED WITH THE EARLIER HEAVY RAINFALL TODAY HAS GREATLY
INCREASED THE LIKELIHOOD OF FLASH FLOODING IN THE LAGARTO AREA. THE
THUNDERSTORM WHICH IS PRODUCING THE HEAVY RAIN HAS SHOWN LITTLE
MOVEMENT. AN ADDITIONAL 1 TO 3 INCHES WITHIN A VERY SHORT TIME IS
LIKELY ACROSS SOUTHERN LIVE OAK COUNTY...INCREASING THE THREAT OF
FLASH FLOODING ALONG CREEKS...RIVERS AND OTHER LOW LYING AREAS.
 
DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THEZ
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.
