POSSIBLE BUT THERE MAY BE ISOLATED AREAS OF 4 TO 6 INCHES. ANY
RAINFALL AMOUNTS OVER 3 INCHES WILL CAUSE FLOODING PROBLEMS.

LIKELY RUN OFF INTO BAYOUS...CREEKS...RIVERS AND LAKES.
TYPICAL LOW LYING AREAS SUCH AS UNDERPASSES COULD FLOOD
QUICKLY WITH RAINFALL RATES OF 1 TO 2 INCHES AN HOUR.
ADDITIONAL RAINFALL COULD PROLONG RIVER FLOODING ACROSS THE
AREA. HEAVY RAINFALL COULD OCCUR OVERNIGHT SATURDAY WHICH WILL
INCREASE THE HAZARDS OF FLOODING. IF FLASH FLOOD WARNINGS ARE
ISSUED IN YOUR AREA...DO NOT DRIVE INTO FLOODED ROADS OR
UNDERPASSES. TURN AROUND DO NOT DROWN.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FLASH FLOOD WATCH MEANS THAT CONDITIONS MAY DEVELOP THAT LEAD
TO FLASH FLOODING. FLASH FLOODING IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION
SHOULD FLASH FLOOD WARNINGS BE ISSUED.
