000 AGXX40 KNHC 111805 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 205 PM EDT Wed Apr 11 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 cold front crosses the basin from Ft Myers Florida near 26N82W to 23N92W, continues as a stationary front to 20N95W, then as a weakening stationary front to just NW of Veracruz near 19N97W. Virtually all of the significant deep convection over the basin has dissipated as strong subsidence sets up over the basin in response to mid- to upper-level ridging building overhead from the NW. Moderate to fresh northeast winds are observed north of the front while light and variable winds are seen over the basin south of the front. The remainder of the front will stall out tonight over the SE Gulf, with the entire front gradually dissipating on Thu. A strong cold front will move off the Texas coast on Sat. Fresh to near gale-force southerly winds preceding the front will become northerly behind the front. Gale force winds are possible across the SW Gulf Sat and Sat night behind the front. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Mainly gentle to moderate trades continue across the basin today. Mid to upper- level ridging extending northward over the basin from South America is maintaining a fairly dry weather pattern and strong subsidence over the Caribbean. Strong nocturnal winds are expected along the coast of Colombia each night Thu night through Sun night, and in the Gulf of Honduras Fri night through Sun night. Fresh to strong trade winds will support large seas over a large portion of the tropical N Atlantic into Sat night. A cold front in the Gulf of Mexico will reach the NW Caribbean Sun night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A cold front extending from 31N74W to south Florida will move SE through tonight, then stall and dissipate across the central Bahamas and the Straits of Florida on Thu. Fresh to strong winds and building seas are expected near the front into Thu morning. An approaching cold front will bring strong to near gale-force southerly winds to the western Atlantic ahead of the front Sun and Sun night. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ017...W CENTRAL GULF FROM 22N TO 26N W OF 94W...
