SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
340 PM CDT SAT JUL 13 2002

...THREAT FOR LOCALLY HEAVY RAINFALL ACROSS MOST OF SOUTHEAST
TEXAS THROUGH SUNDAY...

DEEP TROPICAL MOISTURE FROM THE GULF WILL COMBINE WITH UPPER LEVEL
DISTURBANCES TO PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS ACROSS
SOUTHEAST TEXAS THROUGH SUNDAY. HEAVY DOWNPOURS ASSOCIATED WITH THESE
STORMS COULD PRODUCE RAINFALL RATES OF 2 TO 3 INCHES PER HOUR IN A
FEW SPOTS. THE LOCALIZED HEAVY RAINS COULD LEAD TO HIGH STANDING WATER
ON ROADS AND UNDERPASSES...AND IN AREAS OF POOR DRAINAGE. WATER
LEVELS WILL RISE IN AREAS OF HEAVY RAIN...BUT SIGNIFICANT OVERFLOWS OF
STREAMS AND BAYOUS IS NOT ANTICIPATED.

USE CAUTION WHEN DRIVING IN HEAVY RAIN. DEEP PUDDLES ON ROADS CAN
CAUSE YOUR VEHICLE TO HYDRO-PLANE IF YOU ARE TRAVELING AT HIGH
SPEEDS. HIGH STANDING WATER ON FEEDER ROADS MAY BE TOO DEEP FOR
YOU TO CROSS WITHOUT STALLING. AVOID DRIVING THROUGH HIGH WATER.
