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...A tropical wave currently south of the Mona Passage will move across the central Caribbean through this evening, and across the western Caribbean through Sat. A second tropical wave will enter the eastern Caribbean early this evening into Fri, move across the central Caribbean through Sat, and into the western Caribbean Sun. Building high pressure north of the region will support fresh trade winds and building seas following these tropical waves across the Caribbean by late this week and into early next week, with strong trade winds expected off Colombia by Fri night. E swell associated with the increased trade winds will impact the Atlantic passages of the Windward Islands by this evening. NW Caribbean W of 85W .TODAY...NE winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weak cold front extends from low pressure north of the area near Bermuda through the southern Bahamas. Fresh to strong and rough seas north of 28N and east of 70W will gradually diminish through tonight as the low pressure shifts farther into the north- central Atlantic and the front weakens to a trough. Gentle to moderate breezes and moderate seas will persist into Fri. Farther west, second front will move into the waters between Florida and Bermuda tonight, then stall and dissipate Fri. Looking ahead, strong high pressure will build behind another front expected to move into the waters between Florida and Bermuda early Mon, supporting increased winds and seas across the basin through the early part of next week.
