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 LOCALLY 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 ISOLATED 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.
