 RADAR...AND SURFACE OBSERVATIONS SUGGEST THAT THE CENTER OF BONNIE
 REMAINS POORLY ORGANIZED.  THE CENTER PASSED OVER OR NEAR THE NOAA
 BUOY 42039 EARLIER TODAY PRODUCING GUSTS TO 47 KNOTS AN A 1002.7 MB
 PRESSURE. SATELLITE IMAGES SUGGEST THAT THE CLOUD PATTERN IS
 BECOMING ELONGATED AND IT IS IS BEGINNING TO TRANSITION TO
 EXTRATROPICAL. A PORTION OF THE BROAD CENTER OF CIRCULATION IS
 ALREADY INLAND OVER THE FLORIDA PANHANDLE.
  
 THE CENTER IS MOVING RAPIDLY TOWARD THE NORTHEAST...ABOUT 24 KNOTS.
 ONCE THE CENTER IS COMPLETELY INLAND...WEAKENING SHOULD BEGIN AND
 BONNIE SHOULD BECOME AN EXTRATROPICAL LOW IN ABOUT 24 HOURS OR SO
 AS IT MOVES QUICKLY TO THE NORTHEAST.
