TROPICAL STORM FRANCES DISCUSSION NUMBER  48
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT SUN SEP 05 2004

RADAR DATA AND SURFACE OBSERVATIONS INDICATE THAT THE LARGE CENTER
OF CIRCULATION OF FRANCES CONTINUES TO MOVE SLOWLY ACROSS THE
CENTRAL FLORIDA PENINSULA WHILE WEAKENING. ALTHOUGH THE PRESSURE
REMAINS QUITE LOW...975 MB... THE INITIAL INTENSITY HAS BEEN
DECREASED TO 60 KNOTS. FRANCES IS FORECAST TO CONTINUE MOVING
TOWARD THE WEST-NORTHWEST ABOUT 9 KNOTS AND THEN EMERGE OVER THE
NORTHEASTERN GULF OF MEXICO LATE TONIGHT. BECAUSE FRANCES HAS
MAINTAINED A WELL-DEFINED CLOUD STRUCTURE ON RADAR AND SHOULD BE
OVER WATER FOR 12 HOURS OR SO...IT COULD REGAIN HURRICANE STATUS
AGAIN BEFORE MOVING INLAND WITHIN THE HURRICANE WARNING AREA. THE
OFFICIAL FORECAST IS VERY CLOSE TO THE GLOBAL MODEL CONSENSUS.
