Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...High pressure across the western Atlantic extending a ridge southwestward into the Bahamas will support fresh trades E of 80W through today. The high pressure will then slide SE and across the central Atlantic subtropical waters through the weekend, which will keep mainly moderate to fresh trades across the central and eastern Caribbean through Fri night, and gentle to moderate easterly winds through the weekend. Fresh trades and moderate to rough seas in easterly trade wind swell will prevail over the tropical Atlantic waters and passages through Sat night. Otherwise, pulsing fresh to strong E winds will develop each night across the Gulf of Honduras through the weekend. NW Caribbean W of 85W .TODAY...E winds 10 to 20 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...High pressure across the NW Atlantic extends a ridge southwestward to the Bahamas, while the remnants of a frontal trough persist offshore of Florida along 79W. This pattern is producing moderate to fresh trade winds S of 25N and E of 75W, while light to moderate SE winds prevail elsewhere. The high will slide SE and into the central Atlantic through the upcoming weekend, with ridging extending westward into central Florida. This will gradually lead to anticyclonic winds across the entire area by the weekend. Moderate to fresh trade winds and rough seas in mixed NE and E swell will prevail south of 22N this week, including across the Atlantic passages into the eastern Caribbean.
