SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A STATIONARY FRONT EXTENDS FROM SOUTH OF BERMUDA TO
EAST-CENTRAL FLORIDA. FRESH TO OCCASIONALLY STRONG E WINDS AND
ROUGH SEAS WILL PREVAIL WEST OF 70W THROUGH LATE TONIGHT AS A
STRONG PRESSURE GRADIENT PREVAILS BETWEEN THE FRONT, HIGH
PRESSURE TO THE NORTH AND MAJOR HURRICANE MELISSA IN THE CENTRAL
CARIBBEAN. A LOW PRESSURE SYSTEM ASSOCIATED WITH THE STATIONARY
FRONT WILL PUSH OFFSHORE OF THE SOUTHEASTERN U.S. ON MON,
LEADING TO MODERATE TO FRESH E TO SE WINDS EAST OF 78W MON
AFTERNOON THROUGH TUE, AND FRESH TO STRONG N TO NW WINDS BEHIND
THE SYSTEM OFFSHORE OF NORTHERN FLORIDA TUE THROUGH MIDWEEK.
ROUGH SEAS WILL BUILD OVER THIS REGION BY EARLY TUE, WITH SEAS
EXPANDING FARTHER SOUTH AND EAST TUE AND WED. ELSEWHERE, MAJOR
HURRICANE MELISSA IS STRENGTHENING IN THE CENTRAL CARIBBEAN. ON
THE FORECAST TRACK, THE CORE OF MELISSA IS EXPECTED TO MOVE NEAR
OR OVER JAMAICA ON TUESDAY, ACROSS SOUTHEASTERN CUBA TUESDAY
NIGHT, AND ACROSS THE SOUTHEASTERN BAHAMAS ON WEDNESDAY.
ELSEWHERE, A STRONG COLD FRONT WILL PUSH OFFSHORE OF THE
SOUTHEASTERN U.S. BY LATE WEEK, SUPPORTING INCREASING WINDS AND
BUILDING SEAS OVER THE WESTERN ATLANTIC.
