Atlantic Gale Warnings: A cold front extends from from 31N39W to the northern Windward Islands. Gale-force winds are currently north of 28N within 75 nm east of the front. Rough to high seas accompany the front, as described in greater detail below. The front will shift eastward, with winds over the discussion waters diminishing below gale force today.

Another cold front will impact the SW N Atlantic waters this weekend. Winds have increased to gale force over the waters east of northern Florida ahead of the front. The front will move off the coast of Florida today, and rapidly shift across the forecast waters and exit east of the area through Mon. Gale force winds and rough seas will impact the northern waters in the vicinity of the front through Sun. The front will generate a reinforcing set of NW swell over the Atlantic waters, discussed below.

Gulf of Mexico Gale Warning: A cold front extending from N Florida to the Bay of Campeche. Gale force winds are off the coast of Veracruz, Mexico, with seas peaking near 14 ft. Winds will diminish below gale force early this morning.

Atlantic Significant Swell Event: Large long-period northwest swell with wave periods of 13 to 15 seconds are propagating across the subtropical Atlantic waters. Seas greater than 12 ft associated to this swell cover the waters N of 20N between 31W and 68W. These conditions will propagate eastward across the Atlantic waters, being reinforced by a set of new NW swell as discussed above. Seas are peaking in excess of 20 ft north of 27N between 45W and 59W. Seas of 12 ft or greater are forecast to spread eastward through the weekend.

High pressure will build in the wake of the front across the western Atlantic today. Large, long- period northerly swell will also accompany the front, impacting the Atlantic passages into the northeast Caribbean today, the Atlantic waters east off the Leeward Islands starting tonight, and the waters east of the Windward Islands by early Sun before subsiding into Mon. The pattern will also support moderate to fresh trade winds over the eastern and south- central Caribbean, with strong winds pulsing off Colombia through early next week.

Atlantic Ocean
