  DOPPLER RADAR ESTIMATED FROM 5 TO 7 INCHES OF RAINFALL OVER

  PORTIONS OF WEBB COUNTY. AN ADDITIONAL 2 TO 4 INCHES OF RAINFALL 
  IS STILL POSSIBLE FROM ADDITIONAL SHOWERS AND THUNDERSTORMS.

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
