HURRICANE FRANCES DISCUSSION NUMBER  43
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT SAT SEP 04 2004
 
MIAMI WSR-88D RADAR SHOWS THAT FRANCES HAS DEVELOPED A LARGE EYE OF
ABOUT 70 NMI IN DIAMETER. SATELLITE IMAGES SUGGEST THAT THE CLOUD
PATTERN IS A LITTLE BETTER ORGANIZED AND RECON SUGGESTS THAT AN
EYEWALL MAY BE FORMING. HOWEVER...INITIAL INTENSITY CONTINUES AT 90
KNOTS AND BECAUSE THE HURRICANE HAS ABOUT 12 TO 18 MORE HOURS OVER
WARM WATERS AND THE SHEAR MAY RELAX...THERE IS AN OPPORTUNITY FOR
STRENGTHENING BEFORE LANDFALL.  

RADAR AND RECON INDICATE THAT FRANCES HAS BEEN DRIFTING BETWEEN THE
WEST AND WEST-NORTHWEST AND BECAUSE THE SUBTROPICAL HIGH TO THE
NORTH IS FORECAST TO BUILD FURTHER...A GENERAL WEST-NORTHWEST TRACK
BETWEEN 5 AND 8 KNOTS IS EXPECTED DURING THE NEXT DAY OR TWO. THIS
IS IN AGREEMENT WITH MODEL GUIDANCE WHICH CONSISTENTLY HAS FORECAST 
THE HURRICANE TO MOVE ACROSS FLORIDA. FRANCES HAS A LARGE EYE AND
IS MOVING SLOWLY. THEREFORE...THOSE IN THE PATH OF THE CENTER WILL
EXPERIENCE THE CALM OF THE EYE FOR A LONG PERIOD OF TIME. IN
ADDITION...THIS HURRICANE COULD PRODUCE TORRENTIAL RAINS ALONG ITS
PATH.
