HEAVY RAINFALL OUTLOOK
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
225 PM CDT SAT JUN 21 1997

LOCALLY HEAVY RAINFALL IS POSSIBLE TONIGHT AND SUNDAY OVER
MUCH OF SOUTH TEXAS. THE GREATEST POTENTIAL OF HEAVY RAIN
IS ALONG A LINE FROM VICTORIA TO REFUGIO TO CORPUS CHRISTI
TO KINGSVILLE.  A FLASH FLOOD WATCH IS IN EFFECT FOR TONIGHT
FOR MOST OF SOUTH TEXAS.

AN UPPER LEVEL LOW PRESSURE SYSTEM LOCATED IN SOUTH TEXAS
COMBINED WITH ABUNDANT MOISTURE FROM THE GULF OF MEXICO AND
CONTINUED INSTABILITY IN THE ATMOSPHERE WILL RESULT IN
SCATTERED SHOWERS AND THUNDERSTORMS THROUGH SUNDAY.  THIS
ACTIVITY WILL BE PRIMARILY IN THE COASTAL BEND AND VICTORIA
AREAS THIS AFTERNOON AND WILL SPREAD TO THE RIO GRANDE PLAINS
AREA LATER THIS EVENING.

SHOWERS AND THUNDERSTORMS ARE CURRENTLY LOCATED FROM GOLIAD
TO NORTH OF VICTORIA TO JUST SOUTHWEST OF HOUSTON.  OTHER
ACTIVITY WAS LOCATED FROM BAFFIN BAY TO BROWNSVILLE.  MOST
OF THIS ACTIVITY WAS MOVING NORTH AND NORTHEAST AT 20 TO 25
MPH.  THE POTENTIAL FOR HEAVY RAIN FROM THESE STORMS COMBINED
WITH ALREADY SATURATED SOIL COULD RESULT IN FLASH FLOODING
TONIGHT AND SUNDAY...THEREFORE A FLASH FLOOD WATCH WILL BE
IN EFFECT.
