SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A NEARLY STATIONARY FRONT WILL PERSIST OVER THE NW
WATERS, EXTENDING ROUGHLY FROM 31N74W TO THE NW BAHAMAS AND
SOUTH FLORIDA. THE PRESSURE GRADIENT BETWEEN THE ATLANTIC RIDGE
AND THE FRONT SUPPORTS AN AREA OF FRESH TO STRONG SOUTHERLY WINDS
FROM 25N TO 28N BETWEEN 72W AND 76W. THESE WINDS ARE EXPECTED TO
PERSIST TONIGHT INTO WED. A BAND-LIKE OF SCATTERED TO NUMEROUS
SHOWERS AND THUNDERSTORMS IS SE OF THE FRONT AFFECTING THE
BAHAMAS, THE STRAITS OF FLORIDA AND WESTERN CUBA. WINDS AND SEAS
COULD BE HIGHER NEAR THUNDERSTORMS. ELSEWHERE, THE ATLANTIC RIDGE
WILL CONTINUE TO DOMINATE THE WEATHER PATTERN ACROSS THE
FORECAST WATERS, SUPPORTING GENTLE TO MODERATE WINDS AND MOSTLY
MODERATE SEAS.
