Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...A cold front extends from the Windward Passage to the Gulf of Honduras. The front will reach from the N coast of Hispaniola to the Gulf of Honduras tonight, where it will remain nearly stationary through Fri while weakening. Fresh to strong NE winds W of the front across the northwest Caribbean, including the Gulf of Honduras, will diminish by tonight. Pulsing fresh to locally strong NE winds are expected in the Windward Passage through Sat. Strengthening high pressure N of area will bring an increase in the aerial extent of the fresh to strong trade winds during the upcoming weekend, with the strongest winds near the coast of Colombia. Looking ahead, the next cold front could enter the northwest Caribbean on Mon. NW Caribbean W of 85W .TONIGHT...E winds 10 to 20 kt. Seas 4 to 6 ft. .FRI...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from near 28N50W to the coast of Hispaniola near 19.5N70W. The front will become stationary on Fri, stretching from 22N55W to the N coast of Hispaniola by Fri afternoon, then will remain nearly stationary along 21N on Sat. Strengthening high pressure N of area will push the front farther south on Sun reaching the northern Leeward Islands as a dissipating front. The gale force winds and high seas associated with the front are shifting E of area. The gradient between the strong high pressure along 31N and lower pressure associated with the stalled front will induce fresh to strong NE to E trade winds south of 23N Fri through Sun. On Sun, fresh to strong southerly flow will set up over the waters east of northeast Florida to about 70W in advance of the next cold front. This cold front is expected to move into the NW forecast waters late Sun, followed by fresh to strong northwest winds. Seas will build both east and west of this cold front.
