...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 715 AM CDT FOR WEBB
COUNTY...

AT 639 AM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED 
THAT THUNDERSTORMS PRODUCING FLASH FLOODING OVER THE WARNED AREA 
WERE NOW CONFINED TO AREAS EAST OF INTERSTATE 35...OR FROM RIO BRAVO 
TO 20 MILES EAST OF ENCINAL.

LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO LAS TIENDAS
AND COLUMBIA BRIDGE

ADDITIONAL RAINFALL AMOUNTS OF 1 TO 2 INCHES ARE POSSIBLE IN THE 
WARNED AREA...PRIMARILY ALONG AND SOUTHEAST OF A LINE EXTENDING FROM 
RIO BRAVO TO AGUILARES.

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. MOVE TO HIGHER GROUND.

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.
