000 AGXX40 KNHC 011813 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 213 PM EDT Mon May 1 2017 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 extends from the western Florida Panhandle to near 24N92W, where it becomes stationary to the central Bay of Campeche. The most recent scatterometer pass indicated fresh to strong NW-N winds S of 27N and within abouth 120 nm west of the front with seas of 8-9 ft. Winds and seas will continue to diminish behind the front through late today. The northern portion of the front will reach from the Florida Bing Bend to near 24N90W late today while the southern portion will remain nearly stationary. Then, the front will lift N on Tuesday while dissipating. A weak high pressure will follow the front. Fresh to locally strong southerly return flow will set-up again across the western Gulf by Wednesday, ahead of the next cold front forecast to enter the Gulf waters Wednesday night. Gale force winds are possible again behind the front across the west-central and SW Gulf on Thursday. The next front will reach from SE Louisiana to near Tampico, Mexico early Thursday morning, and from near Tampa Bay, Florida to the eastern Bay of Campeche by Thursday night. At that time, fresh to strong notherly winds will follow the front, forecast to reach the SE Gulf on Friday. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A ridge located north of the area continues to support overnight and early morning hours pulses of fresh to strong E-SE winds near the Gulf of Honduras, easterly trade winds off Colombia and northwest Venezuela and a smaller area south of Cabo Beata in southern Dominican Republic. The high pressure is forecast to shift eastward over the next 24 hour, reaching a position near 33N55W by Tuesday morning. As a result, a small area of fresh to strong trades will persist mainly near northwest Venezuela, including also the Gulf of Venezuela, through Tuesday morning. Winds and seas will diminish across the region through the middle of the week as the high pressure weakens and shifts east, leaving mainly fresh trades off Colombia and gentle to moderate breezes elsewhere. ...SW N ATLANTIC INCLUDING THE BAHAMAS... An area of cloudiness with scattered showers and isolated thunderstorms extends over the SE waters covering roughly from Puerto Rico and the Mona Passage to 24N between 65W and 71W. The most recent ASCAT pass suggests the presence of a surface trough extending from 24N68W to eastern Dominican Republic. Fresh to locally strong winds and seas to 8 ft are associated with this trough, forecast to move W-NW across the Bahamas over the next 24-48 hours. Winds and seas will diminish late on Tuesday as the trough reaches the SE Bahamas. Otherwise, high pressure of 1026 mb located over the NE waters and SW of Bermuda extends a ridge across the SW N Atlantic and the Florida Peninsula. Under the influence of this system, gentle to moderate winds are noted north of 27N, moderate to fresh winds can be found between 24N and 27N, while fresh to strong E-SE winds continue to blow south of 24N from the Turks and Caicos Islands, across the southern Bahamas to the Straits of Florida. Southeast to south winds will increase through tonight between northeast Florida the the northern Bahamas between ridging to the east and a cold front approaching from the west. The ridge will shift eastward, allowing the stronger winds to the south to diminish slightly. The front will drift off the coast of northeast Florida early Tuesday morning, allowing the southerly winds between northeast Florida and the northern Bahamas to diminish. The front will continue east, eventually stalling and dissipating from 31N73W to the northern Bahamas through mid week. Into Thursday, a weaker ridge will build westward along 29N/30N maintaining gentle to moderate breezes and slight seas. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ023...SW GULF S OF 22N W OF 94W...
