* FROM FRIDAY AFTERNOON THROUGH SUNDAY MORNING
* UNUSUALLY MOIST TROPICAL AIR WILL STREAM INTO THE REGION FRIDAY
AS SOUTHERLY WINDS INCREASE. AN UPPER LEVEL JETSTREAM WILL BRING

RAINFALL IS POSSIBLE AFTER THAT AND THE GROUND WILL BE SATURATED
AND STREAMS AND BAYOUS MAY ALREADY BE SWOLLEN OR FLOODING.
WIDESPREAD RAINFALL TOTALS THROUGH THE WATCH PERIOD WILL LIKELY
AVERAGE 2 TO 4 INCHES WITH LOCALIZED AMOUNTS OF 5 TO 8 INCHES.
MUCH OF THESE AMOUNTS COULD COME IN ONLY A FEW HOURS OF HEAVY
RAIN. AS WE APPROACH THE WATCH PERIOD CONFIDENCE IN TIMING AND
LOCATION WILL LIKELY IMPROVE THE FOCUS FOR WHERE THE HEAVY RAINS
WILL FALL.
* STREETS...BAYOUS...STREAMS AND RIVERS WILL LIKELY HAVE THE
GREATEST IMPACTS FROM THE HEAVY RAINFALL. MOTORISTS AND PERSONS
WITH OUTDOOR ACTIVITIES SHOULD STAY ABREAST OF THE LATEST
FORECASTS AND HAVE CONTINGENCY PLANS FOR WHEN THE HEAVY RAIN
ARRIVES.
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.
