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
AND DISSIPATES. STRONG SOUTHERLY WINDS AND ROUGH SEAS WILL FOLLOW
THE DYING 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.
LOOKING AHEAD, MELISSA WILL IMPACT ATLANTIC WATERS AROUND THE
SOUTHERN BAHAMAS AND TURKS AND CAICOS TUE NIGHT AND WED. FARTHER
NORTH, A WEAK COLD FRONT WILL MOVE OFF THE NORTHEAST FLORIDA
COAST MON NIGHT, THEN STALL AND DISSIPATE. A STRONGER REINFORCING
COLD FRONT WILL MOVE OFF THE NORTHEAST FLORIDA COAST BY LATE
WED.
