Winds reaching minimal gale force winds are ongoing along the coast of Veracruz Mexico following a late season cold front extending from Mobile Bay to the southwest Gulf near 18N94W. A line of showers and thunderstorms is ahead of the front north of 25N, moving eastward across the northeast Gulf. Seas of 10 to 15 ft are noted over the western Gulf in the wake of the front supporting by strong northerly winds. The exception is over the fetch limited far northwest Gulf where seas are 3 to 5 ft over coastal waters and 5 to 7 ft farther offshore. The gale winds off Veracruz will diminish early this morning as the front shifts east. The front sweeps southeast of the Gulf through tonight. Winds and seas diminish into Mon as high pressure builds across the basin and persists through mid week. A weaker cold front is forecast to stall and dissipate over the northern Gulf Thu. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Fresh to strong SE winds are ongoing over the northeast and south central Caribbean ahead of a late season cold front moving through the Gulf of Mexico. Recent scatterometer passes indicate fresh to strong E to SE winds off northeast Colombia and near the Gulf of Honduras. Seas over the south central Caribbean are likely 8 to 10 ft, with 5 to 8 ft elsewhere. A recent altimeter satellite pass showed NE to E swell over the tropical Atlantic has largely decayed below 8 ft. No significant convection is observed at this time. The cold front will enter the NW Caribbean late today, and stall from central Cuba to central Honduras by early Mon, before dissipating through late Tue. The strong E to SE winds off Honduras will diminish as the ridge north of the area shifts eastward ahead of the front. But strong NW winds will follow the front from the coast of Quintana Roo to the Gulf of Honduras, before diminishing Mon. Elsewhere, the fresh to strong trade winds will continue to pulse near the coast over the south central Caribbean through mid week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... High pressure northeast of the area is supporting pulses of fresh to strong trade winds off Hispaniola, as noted in recent scatterometer imagery and ship observations. The strong winds are noted mainly along the northern coast of Haiti as far west as the approaches to the Windward Passage. Recent buoy and altimeter data show seas of 8 to 9 ft south of 22N and east of the Turks and Caicos. SE to S winds are starting to increase to fresh to strong W of 75W ahead of a cold front moving off the northeast Florida coast late this afternoon, then increase to minimal gale force west and east of the front north of 30N tonight. Winds will diminish Mon as the front moves east and reaches from 30N72W to central Cuba Mon evening, and from Bermuda to eastern Cuba late Tue, then lifting north to 25N and dissipating through mid week. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
