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...Trade winds will pulse to fresh to locally strong speeds offshore of Colombia and through the Gulf of Venezuela each night and morning this week, as low pressure prevails over northwestern Colombia. A strengthening pressure gradient between a cold front moving southeastward through the Gulf of America, the Colombian low, and high pressure over the western Atlantic will support fresh to locally strong NE winds through the Windward Passage overnight, and fresh to strong SE winds in the Gulf of Honduras through Wed morning. The aforementioned cold front will enter the northwestern Caribbean Wed night into Thu and gradually weaken, leading to moderate to locally fresh N to NE winds behind the front. Otherwise, moderate trade winds and slight to moderate seas are expected across the central and eastern Caribbean into this weekend. NW Caribbean W of 85W .TONIGHT...SE winds 10 to 20 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Fresh to strong SE winds will occur tonight north of 25N and west of 75W ahead of a cold front moving through the southeastern United States. Winds will strengthen to gale force Wed morning offshore of northeastern Florida as the front pushes off the coast and rapidly progresses eastward. Gale force winds will continue along and ahead of the front through Thu night north of 29N. Behind the front, gale force NW winds are expected Thu morning through Thu night north of 29N. N swell associated with this system will propagate southeastward through late week, producing rough seas north of 25N through Thu, and north of 22N through Fri. Peak seas of 15 to 19 ft are anticipated north of 27N between 78W and 60W through late this week. The storm system will progress eastward across the central Atlantic through Fri before lifting north and east of the forecast waters. Elsewhere, fresh to strong NE winds and rough seas will prevail north of a cold front, extending from 31N47W to 21N70W, overnight through Wed. Otherwise, moderate to fresh trades and rough seas will prevail south of 25N this week.
