000 AGXX40 KNHC 260623 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 123 AM EST Mon Feb 26 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... Surface ridging prevails across most of the basin, anchored by a 1026 mb high centered over the west Atlantic. With this, fair weather dominates the area. Over the far northwest portion of the basin, a low pressure system is developing along the coast of Texas. A pair of 1011 mb lows are located near 29N96W and 27N98W. A weak cold front will move into the NW Gulf this morning behind these lows, then stall and weaken from the FL panhandle to NE Mexico through tonight. High pressure will build across the region Tue. Another, stronger cold front will move into the NW Gulf Wed night. Gale conditions are possible over the SW Gulf Thu afternoon and Thu night behind this front. This cold front will exit the SE Gulf late Fri, while stalling over the western Gulf. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Stable and fair weather conditions dominate the Caribbean at this time as a broad area of high pressure extends across the area from the north. An upper-level low is centered north of Hispaniola extending a trough across the central Caribbean. Scattered showers are noted over the Mona Passage and Puerto Rico coastal waters supported by a diffluent flow aloft. High pres N of the area will support fresh to strong trade winds along the coast of Colombia throughout the period. Similar winds will pulse in the Windward Passage, and along the SE coast of Hispaniola through Wed night. The high pressure will weaken midweek which will allow the winds over the northern Caribbean to become light. A cold front may reach the NW Caribbean late Fri. Northerly swell of 8 to 10 ft will affect the tropical Atlantic waters beginning Wed, reaching the Atlantic passages E of 65W Wed night through Fri. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A broad surface ridge prevails across the west and central Atlantic anchored by a 1026 mb high near 30N67W. The pressure gradient to the south of this high will help cause moderate to fresh winds to pulse to fresh to strong at night during the next several days. The area of high pressure will slowly weaken and shift southeastward through Tue. A cold front will move off the SE coast of the U.S. Tue, and reach the central Bahamas Wed evening. High pressure will build N of the front Wed evening. Strong return flow will reach the zones E of 70W Thu. A stronger cold front will begin to affect waters N of 28N Thu night. A strong low pressure system N of the area will likely bring a significant swell event to the SW N Atlantic waters by this weekend. $$ .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...
