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...Fresh to strong NE to E winds will pulse offshore of Colombia and in the Gulf of Venezuela each night and morning through midweek as low pressure prevails over northwestern Colombia. A tightening pressure gradient between the Colombian low, a front moving through the central Atlantic, and building high pressure in the western Atlantic will support fresh NE winds through the Windward Passage and in the lee of Cuba tonight into early Wed, and fresh to strong E to SE winds in the Gulf of Honduras Tue night into Wed. Otherwise, moderate trade winds and slight to moderate seas are expected across the central and eastern Caribbean through the week. NW Caribbean W of 85W .TODAY...E winds less than 10 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 31N63W to 21N75W will progress to the south and east through Tue before dissipating midweek. A brief period of gale force winds are expected through this afternoon in the vicinity of the front and north of 30N. Behind the front, fresh to strong N winds and rough seas will occur today north of 26.5N between 60W and 75W. Rough seas in N to NW swell will propagate through much of the open waters early this week, with seas in excess of 8 ft north of 26N by late morning, and north of 22N Tue morning. Fresh to strong trade winds and rough seas are likely south of 25N today, then moderate to fresh trades are expected through the rest of the week. Elsewhere, high pressure building over the eastern United States will support fresh to strong E to SE winds off the coast of Florida and through the Bahamas by early Tue. More widespread fresh to strong S winds will develop in this region Tue night ahead of a strong cold front entering the northwestern basin on Wed. Strong to near-gale force winds and rough to very rough seas are expected surrounding the associated low pressure system as it moves eastward, and gale force winds will be possible behind the cold front late week.
