THE CYCLONE IS ENCOUNTERING INCREASING WESTERLY UPPER-LEVEL WINDS...WHICH WILL LIKELY LEAD TO THE SYSTEM SHEARING APART DURING THE NEXT 24-36 HR. THUS...CONTINUED WEAKENING IS FORECAST UNTIL THE SYSTEM DISSIPATES IN ABOUT 48 HR. THE INITIAL MOTION REMAINS 040/10. ALL GUIDANCE FORECASTS A GRADUAL TURN TOWARD THE EAST DURING THE NEXT 24-36 HR...AND THE FORECAST TRACK FOLLOWS THIS SCENARIO. IT SHOULD BE NOTED THAT MUCH OF THE GUIDANCE FORECASTS THE REMNANTS OF HUMBERTO TO TURN SOUTH AND SOUTHWESTWARD AFTER 36 HR...POSSIBLY RE-EMERGING INTO THE GULF OF MEXICO. WHILE THIS IS POSSIBLE...IT IS LIKELY THE REMNANTS WILL BE TOO WEAK TO RE-GENERATE. THIS IS THE LAST ADVISORY ON HUMBERTO BY THE NATIONAL HURRICANE CENTER.
