000 AGXX40 KNHC 061939 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 239 PM EST Mon Nov 6 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... Light breezes and slight seas will persist over the NE Gulf the next few days near the center of high pressure. Mainly gentle to moderate winds and 2 to 4 ft seas will persist elsewhere. SE return flow will increase briefly today over the NW Gulf ahead of lower pressure forming over Texas. Fresh northerly flow and seas building to 6 ft will follow a cold front moving off the Texas coast on Wednesday, reaching a position from the Florida Big Bend area to NE Mexico on Thursday, before stalling and weakening from SW Florida to near Tampico Mexico through Fri. as strong high pressure builds southward over the E Gulf, and over the eastern portion of the central Gulf. Scattered showers are possible ahead of the front. Fresh NE winds will persist over the northern Gulf through Fri. These winds then become fresh to locally strong Fri. night through Sat. night in response to the building strong high pressure. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure building to the north will maintain moderate trades from the tropical N Atlantic into the central Caribbean through mid week, with local and brief pulses to 20 kt along the South American coast at night, and possibly in the Lee of Cuba Tue through Sat. Global models suggest that weak low may emerge off the coast of Colombia Tuesday night, and move NW through Fri. before moving in a SW direction Fri. night through Sat. night as high pressure from the Gulf of Mexico surges southward across the NW Caribbean Sea and Cuba., ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weak trough off the east coast of Florida and through the northern Bahamas will dissipate through mid week. High pressure over the central Atlantic will build westward through mid week along roughly 28N, supporting moderate trades S of 22N, pulsing to 20 kt off the north coast of Hispaniola tonight and Mon night. Otherwise modest winds and seas will persist through about Wed. to the N of 22N. Models agree on showing a rather weak cold front that slowly moves southeastward over the southeastern United States on Wednesday, and into the far NW portion of the area early on Thu. Models disagree to some extent with timing in the eastward motion of the front thereafter. By Thu. night, the front is expected to be near a position from near 31N72W to near Daytona Beach Florida, reach from near 31N68W to near 28N75W and stationary to near Cape Canaveral by early Fri. afternoon, and as a weakening cold front from near 30N65W and stationary to near 27N72W, and dissipating stationary to vicinity of Cape Canaveral on Saturday as strong high pressure ridging that builds behind the front will tend to bridge across the stationary frontal portion with the related pressure gradient to induce fresh to strong NE to E winds that will press southward over just about the entire basin into Sunday. Seas will significantly build on days 4 and 5 over the waters N and NE of the Bahamas. This is indicated in the latest TAFB gridded forecast. Expect pretty rough marine conditions over those waters. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
