Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...A 1025 mb high near and east of the Bahamas will help maintain fresh to strong trades across the central Caribbean for the next several days. Winds will pulse to gale-force off the coast of Colombia during evening and early morning hours through Sat night. The coverage area of the fresh to strong trades is expected to diminish beginning Sun as the high pressure weakens. Fresh to strong NE to E winds will also occur in the Windward Passage and lee of Cuba through Sun. Strong to near gale E to SE winds in the Gulf of Honduras will continue through Sun morning. Looking ahead, large long-period N swell may begin impacting the tropical N Atlantic zones starting Sun night. NW Caribbean W of 85W .TONIGHT...E winds 15 to 25 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A high pressure ridge between the Bahamas and Bermuda will help maintain fresh to strong trades north of Hispaniola and gentle to moderate winds elsewhere through Sat night. A surface trough stretching westward across western Atlantic north of Pareto Rico will dissipate by Fri morning. A stronger cold front will move across the western Atlantic waters near 28N Fri night, extend from near 31N55W to 28N65W to 31N78W Sat morning, and weaken as it reaches from near 24N55W to 24N65W Sun morning. Strong NW to N winds are likely on Sat across the western Atlantic waters behind the front, with large N swell propagating southward east of 65W though Mon night. Looking ahead, another cold front should arrive over the NE waters on Sun, causing strong breeze to near gale conditions on both sides of the front north of 27N through Mon night. NE swell producing large seas is expected behind this front. ATLC waters from 27N to 31N W of 77W .TONIGHT...SW winds 10 to 15 kt. Seas 3 to 4 ft. .FRI...W winds less than 10 kt.
