Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Fresh to strong NE winds will persist in the Windward Passage through tonight. Strong high pressure N of the area will continue to bring a large area of strong trade winds across the central Caribbean Sea through tonight, with near-gale force winds near the coast of Colombia. Fresh to strong winds are expected over the south-central Caribbean most of the forecast period. Looking ahead, the next cold front will enter the northwest Caribbean early Mon, followed by fresh N to NE winds with seas building to 8 to 11 ft in the Yucatan Channel. The front will stall over the NW Caribbean early in the week before retreating back north of the basin as a warm front by mid-week. NW Caribbean W of 85W .TONIGHT...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weakening stationary front extends from near 22N55W to 21N70W. The pressure gradient between the strong high pressure along 31N and lower pressure associated with the dissipating front will continue to produce fresh to strong NE to E trade winds south of 24N 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. Strong to near-gale force winds are likely on both sides of the front, with brief gales possible Sun night N of 29N between NE Florida and 73W. Seas will build ahead and behind the cold front. The front is forecast to stall late Mon night from Bermuda to central Cuba. By mid- week, the front is expected to lift N as a warm front. The pressure gradient between very strong high pressure north of the area and lower pressure associated with the warm front may induce fresh to strong NE to E winds and building seas to the east of Florida by mid-week ATLC waters from 27N to 31N W of 77W ...GALE WARNING... ...GALE CONDITIONS POSSIBLE... .TONIGHT...SE winds 10 to 20 kt.
