EVENT...OUTER BANDS OF HURRICANE DEAN CONTINUE TO BRING RAINS TO PR
.
SATELLITE ANALYSIS AND TRENDS...EMBEDDED TSTORMS WITHIN THE OUTER
RAINBANDS OF DEAN CONTINUE TO MOVE ACROSS THE ISLAND FROM SE-NW. FOR THE
MOST PART THOUGH..RAINS OVER THE ERN HALF OF THE ISLAND HAVE LIGHTENED
UP WITH EXCEPTION OF TSTORMS MOVING N/NW AND ORIENTED FROM OROCOVIS/N
COAMO TO SAN JUAN. ESTIMATES FROM THE HYDROESTIMATOR SHOWED RAINRATES
OF .7-1"/HR WHILE THEY WERE OVER WATER BUT WITH FAST MOVEMENT OF CELLS
SHOULD NOT BE MUCH CAUSE FOR ALARM EXCEPT FOR LOCAL AREAS THAT ALREADY
RECEIVED HVY RAINS. AM MORE CONCERNED WITH NEW RAINBAND THAT IS FORMING
S/SW OF THE ISLAND AS IT LOOKS AS THOUGH IT COULD MIGRATE FAR ENOUGH
N AND HOLD ITSELF TOGETHER TO PRODUCE HVY TRAINING RAINS OVER THE
SW PART OF THE ISLAND IN A FEW HRS TIME. IR IMAGERY SHOWS THIS BAND
ENHANCING WITH CLOUD TOPS WSW OF CABO ROJO HAVING REACHED -79C. PER VIS
IMAGERY..LOOKS AS THOUGH REMNANTS OF OLD WEAKENING BAND WILL MERGE WITH
THE NEWLY FORMING BAND AS IT MOVES NWD. EMBEDDED TSTORMS WITHIN BAND
CAN BE SEEN ON RADAR AND ESTIMATE THAT WITH OVER 2" PW VALUES STILL IN
AREA...RAINFALL AMOUNTS OF 2-4" MAY BE POSSIBLE STARTING AROUND 20-21Z
IF THIS BAND HOLDS TOGETHER LONG ENOUGH TO REACH THE SW MUNICIPALITIES.
