HEAVY RAIN HAS CONTINUED ACROSS UVALDE...MEDINA...BEXAR AND ATASCOSA

WESTERN TEXAS. WIDESPREAD SHOWERS AND THUNDERSTORMS HAVE PRODUCED
GENERAL RAIN ACCUMULATIONS OF 1 TO 2 INCHES OVER THE FOUR COUNTY AREA

NUMEROUS REPORTS HAVE BEEN RECEIVED OVER OVER 4 INCHES OF RAIN.  MANY
OF THE EXITS ALONG INTERSTATE ROADS ARE FLOODED AND IMPASSABLE AND
MANY LOW-LYING AREAS AND SECONDARY ROADS ARE ALREADY BARRICADED.
 
MOTORISTS MUST NOT ATTEMPT TO DRIVE THROUGH DEEP WATER...SINCE IT IS
ALMOST ALWAYS DEEPER AND MOVING MORE RAPIDLY THAN IT APPEARS TO BE.
 
REMEMBER...MOST SOUTH TEXAS WEATHER-RELATED DEATHS ARE DUE TO
MOTORISTS TRYING TO CROSS FLOODED ROADS AND LOW AREAS AND TO CHILDREN
PLAYING IN AND NEAR FLOODED CREEKS AND DITCHES.
 
A FLASH FLOOD WARNING MEANS THAT RFLOODING IS IMMINENT OR HAS BEEN
REPORTED.
