SYNOPSIS
A STATIONARY FRONT EXTENDS FROM BERMUDA
SOUTHWESTWARD TO SOUTH FLORIDA. FRESH TO OCCASIONALLY STRONG E
TO NE WINDS WILL OCCUR WEST OF 70W THROUGH SUN MORNING AS THE
PRESSURE GRADIENT PREVAILS BETWEEN HIGH PRESSURE BUILDING OVER
THE NORTHEASTERN UNITED STATES AND HURRICANE MELISSA IN THE

CENTRAL FLORIDA AND NORTH AND EAST OF THE BAHAMAS. WINDS AND SEAS
WILL SLOWLY DIMINISH SUN INTO EARLY NEXT WEEK AS THE FRONTAL
BOUNDARY LIFTS NORTHWARD. A WEAK FRONT WILL MOVE OFF THE
NORTHEAST FLORIDA COAST TUE THEN STALL AND DISSIPATE, AHEAD OF A
STRONGER REINFORCING FRONT THAT WILL MOVE OFF THE NORTHEAST
FLORIDA COAST LATE WED. FARTHER SOUTH, HURRICANE MELISSA IS
STRENGTHENING IN THE CENTRAL CARIBBEAN NEAR JAMAICA. RAPID
INTENSIFICATION IS FORECAST TO OCCUR OVER THE NEXT COUPLE OF DAYS
AND MELISSA MAY BECOME A MAJOR HURRICANE TONIGHT OR EARLY SUN.
MELISSA IS FORECAST TO MOVE ACROSS EASTERN CUBA LATE TUE INTO
WED, THEN PASS OVER THE SOUTHERN BAHAMAS LATE WED INTO THU,
BEFORE RAPIDLY MOVING TO THE SOUTHEAST OF BERMUDA BY LATE THU.
