| #6397 (Received by flhurricane at: 10:45 PM 28.Aug.2004) TCDAT1 HURRICANE FRANCES DISCUSSION NUMBER 17 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 11 PM EDT SAT AUG 28 2004 INTENSITY ESTIMATES FOR FRANCES ARE ALMOST IDENTICAL TO THE LAST FORECAST CYCLE SO THE INITIAL INTENSITY WILL REMAIN AT 115 KT. THE INITIAL MOTION IS 300/08. FRANCES REMAINS ON TRACK AND CONTINUES TO TURN BACK TOWARD THE WEST-NORTHWEST. THERE IS LITTLE CHANGE TO THE PREVIOUS TRACK FORECASTS OR REASONINGS. MOST OF THE NHC MODEL GUIDANCE AGREES ON GRADUALLY BUILDING THE SUBTROPICAL RIDGE WESTWARD TO THE NORTH OF FRANCES THROUGHOUT THE FORECAST PERIOD. WITH THE CONTINUED SLOWER MOTION IN THE EARLY FORECAST PERIODS...MINOR ADJUSTMENTS ARE MADE TO THE 4 AND 5 DAY FORECAST POSITIONS. FRANCES IS EMBEDDED IN A LOW-SHEAR ENVIRONMENT WITH EXCELLENT OUTFLOW IN ALL QUADRANTS. THE SSTS ARE NEAR 29C...AND ADDITIONAL INTENSIFICATION SHOULD OCCUR. IT IS POSSIBLE THAT FRANCES COULD REACH CATEGORY 5 INTENSITY AT ANY TIME DURING THE FORECAST PERIOD.
