SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A TIGHT PRESSURE GRADIENT BETWEEN CENTRAL ATLANTIC
HIGH PRESSURE AND TROPICAL STORM MELISSA IN THE CENTRAL
CARIBBEAN HAS RESULTED IN STRONG TO NEAR GALE FORCE EAST TO
SOUTHEAST WINDS ALONG THE COAST OF HISPANIOLA AND EXTENDING
NORTHWARD TO THE VICINITY OF THE SOUTHEASTERN BAHAMAS. THESE
WINDS ARE EXPECTED CONTINUE UNTIL EARLY FRI MORNING. OTHERWISE, A
COLD FRONT EXTENDS FROM NEAR 31N74W SOUTHWESTWARD TO PALM BEACH
FLORIDA. THIS FRONT IS EXPECTED TO TALL FROM NEAR BERMUDA TO
SOUTHERN FLORIDA BY FRI NIGHT. HIGH PRESSURE BUILDING IN BEHIND
THE FRONT WILL SUPPORT STRONG NORTHEAST TO EAST WINDS AND ROUGH
SEAS NORTH OF THE BOUNDARY FRI THROUGH SUN WHILE IT WEAKENS.
THESE WINDS AND SEAS WILL DECREASE ON MON AS THE FRONT WEAKENS.
WINDS AND SEAS ARE ONCE AGAIN EXPECTED TO INCREASE AFTER MON
NIGHT AS HIGH PRESSURE BUILDING IN THE WAKE OF A WESTERN ATLANTIC
COLD FRONT INTERACTS WITH WHAT IS EXPECTED TO BE MAJOR HURRICANE
MELISSA APPROACHING EASTERN CUBA AT THAT TIME.
