Pulsing fresh to strong trade winds and rough seas are then expected across the eastern and central basin this weekend as high pressure drifts eastward into the central Atlantic. Elsewhere, fresh to strong E to SE winds will pulse in the Gulf of Honduras through this weekend. Looking ahead, a tropical wave, currently analyzed east of the Lesser Antilles, will trek westward into the central Caribbean this weekend.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Moderate to fresh S to SW winds will develop offshore of Florida and north of the Bahamas by early Fri as a strengthening pressure gradient develops between high pressure in the eastern Gulf of America and a cold front moving through the southern U.S. Fresh to strong SW winds and rough seas are expected north of 28N and west of 65W by early Sat as the front pushes offshore into the western Atlantic. Winds will turn to the W and slowly diminish behind the front Sat through Sat night, before the front weakens and lifts northeastward on Sun. Elsewhere, moderate to fresh trade winds will pulse south of 23N through Fri. Looking ahead, high pressure is slated to build over the central and western Atlantic Sun into next week.
