COUNTIES...INCLUDING PARTS OF BROWNSVILLE...LOS FRESNOS...SAN BENITO...
HARLINGEN AND RAYMONDVILLE REMAIN UNDER WATER. HEAVY RAINFALL TOTALS
OF 10 INCHES OR MORE IN SOME LOCATIONS THE PAST COUPLE OF DAYS HAVE

WHILE HEAVIER RAINS HAVE TAPERED OFF...THE WATER CURRENTLY FLOODING AREA
ROADS WILL BE SLOW TO RECEDE. ADDITIONAL HEAVY RAINS COULD DEVELOP
BEFORE THE TROPICAL DEPRESSION MOVES FAR ENOUGH EAST TO BRING THE RAIN
THREAT TO AN END OVER THE VALLEY. THAT MAY FINALLY TAKE PLACE BY SUNDAY
NIGHT OR MONDAY WHEN DRIER AIR IS EXPECTED FROM THE NORTH.
 
 
 
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.
