MORE THAN TWICE THE SIGNIFICANT WAVE HEIGHT.
SYNOPSIS FOR CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM
07N TO 19N W OF 55W
SYNOPSIS
THE PRESSURE GRADIENT BETWEEN ATLANTIC HIGH PRESSURE
AND LOWER PRESSURE OVER COLOMBIA WILL CONTINUE TO ALLOW FOR
FRESH TO STRONG WINDS AND ROUGH SEAS OVER THE CENTRAL CARIBBEAN
THROUGH TUE NIGHT. THE STRONGEST WINDS WILL OCCUR OFF THE COAST
OF COLOMBIA, OCASSIONALLY PULSING TO NEAR GALE-FORCE AT NIGHT.
MODERATE TO FRESH TRADES WILL PREVAIL OVER THE E CARIBBEAN WHILE
MODERATE OR WEAKER WINDS ARE FORECAST FOR THE NW CARIBBEAN. A
TROPICAL WAVE ACCOMPANIED BY SCATTERED SHOWERS AND THUNDERSTORMS,
AND LIKELY GUSTY WINDS, IS EXPECTED TO MOVE THROUGH THE TROPICAL
