000 AGXX40 KNHC 050828 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 328 AM EST Mon Feb 5 2018 Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea, and Tropical North Atlantic from 07N to 19N between 55W and 64W and the Southwest North Atlantic including the Bahamas ...GULF OF MEXICO... A few showers and thunderstorms are ongoing over the southeast Gulf ahead of a cold front reaching from the Florida Big Bend area to the central coast of Texas. The showers and thunderstorms will weaken and shift eastward through the early morning. Platforms over the northwest Gulf are reporting areas of fog with visibilities around 4 nm. This will clear up later this morning as drier air filters into the region behind the front. Seas are 3 to 5 ft across the region. The front will continue to move south before stalling from South Florida to South Texas later today. The front will dissipate as it lifts northward over the western Gulf through early Tue, ahead of another cold front moving into the northwest Gulf late Wed. Fresh to strong northerly winds and seas building to 8 ft will follow the front mainly off the coast of Mexico as the front reaches a position from central Florida to the southwest Gulf by late Thu before lifting northward over the western Gulf and weakening Fri. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure north of the area is supporting gale force winds off the coast of Colombia, as verified by vessel 9HA3047 earlier. Seas are 8 to 11 ft over much of the south central and southwest Caribbean, and generally 5 to 7 elsewhere in the Caribbean. Recent buoy observations over the tropical Atlantic indicate NE to E swell and locally derived wind waves due to fresh trade wind flow have reached the Leeward and Windward Islands and may be pushing into exposed Atlantic passages. No significant convection is observed due to mainly zonal westerly flow aloft, but fast- moving trade wind showers are likely from the tropical north Atlantic west of 55W through the southwest Caribbean. The pattern will continue to support fresh to strong winds off Colombia, the Windward Passage and in the lee of Hispaniola through Fri, pulsing to gale force off Colombia each night. High pressure building over the central Atlc will continue to support fresh trades east of the Leeward and Windward Islands, accompanied by NE to E swell in excess of 8 ft. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A cold front is moving off the northeast Florida coast. Scattered showers and a few thunderstorms are noted in advance of the front, as are fresh to strong southerly flow north of 30N. Recent buoy observations and altimeter satellite passes indicate 5 to 7 ft seas in open waters. The front will reach from Bermuda to South Florida by late today, stall from 29N65W to the Straights of Florida late Tue, then dissipate by mid week. High pressure will build behind the front, supporting fresh to occasionally strong E winds south of 22N by mid week. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
