SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A STATIONARY FRONT REACHES FROM BERMUDA TO SOUTH
FLORIDA. A TIGHT PRESSURE GRADIENT BETWEEN HIGH PRESSURE NORTH
OF THE FRONT AND TROPICAL STORM MELISSA WILL SUPPORT FRESH TO
STRONG NE WINDS AND ROUGH SEAS NORTH OF THE FRONT AND OFF THE
CENTRAL BAHAMAS THROUGH SUN AS THE FRONT LIFTS NORTH OF THE AREA.
STRONG SOUTHERLY WINDS AND ROUGH SEAS WILL FOLLOW THE FRONT
BETWEEN NORTHEAST FLORIDA AND BERMUDA LATE MON AND TUE. LOOKING
AHEAD, TROPICAL STORM MELISSA, CURRENTLY SOUTH OF HAITI AND
JAMAICA, IS FORECAST TO INTENSIFY TO A MAJOR HURRICANE AND MOVE
ACROSS JAMAICA AND EASTERN CUBA MON AND TUE. MELISSA MAY THEN
POSSIBLY IMPACT ATLANTIC WATERS AROUND THE SOUTHERN BAHAMAS AND
TURKS AND CAICOS BY WED.
