SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
HIGH PRESSURE WILL DOMINATE THE WEATHER PATTERN
THROUGH THE PERIOD, PROMOTING A GENTLE TO MODERATE ANTICYCLONIC

TO SE WINDS WITH MODERATE SEAS THAT IS CURRENTLY MOVING WESTWARD
ACROSS THE WATERS NORTH OF PUERTO RICO. WINDS AND SEAS ASSOCIATED

WEAKENS SLIGHTLY.
