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 over the eastern Caribbean will move across the central Caribbean through through late Thu, and across the western Caribbean through Sat. A second tropical wave will enter the eastern Caribbean late Thu into Fri, move across the central Caribbean through Sat, and into the western Caribbean Sun. Looking ahead, 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. Another round of E swell associated with the increased trade winds will impact the Atlantic passages of the Windward Islands by late Thu. NW Caribbean W of 85W .TODAY...N winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Winds to minimal gale force persist northeast of the 1007 mb low pressure that is the remnant low of Oscar centered east of the central Bahamas near 25N69W. The low pressure is part of a bigger trough that reaches toward Bermuda. The low will continue to develop into a large gale center that will move to the west of Bermuda by late today and farther into the north central Atlantic Thu. This will pull in slightly cooler and drier air on the west side of the low, forming a cold front that will extend from the low pressure through the Bahamas late today, then sweep to the east of region by Sat. Gale force winds will shift north of 31N today, and winds and seas will diminish across the entire basin into Thu as the gale center lifts farther northward. A reinforcing cold front will follow, but will start to dissipate as it enters the waters between Florida and Bermuda by late Fri. Looking ahead, another cold front may move into the waters off northeast Florida by late Sun. ATLC waters from 27N to 31N W of 77W .TODAY...NE winds 10 to 15 kt.
