000 AGXX40 KNHC 200757 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 257 AM EST Sun Jan 20 2019 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 strong cold front extends SSW from near the mouth of the Suwannee River in Florida to the northern coast of the Yucatan Peninsula near 21.5N88.5W to the SE Bay of Campeche near 18.5N92W. Showers and thunderstorms are occurring along and up to 90 nm E of the front N of 23N. Fresh to strong SW to S return flow lingers over the SE corner of the Gulf. High pres is building over the Gulf in the wake of the front, but gale-force winds will continue along the coast of Mexico near Veracruz until around sunrise this morning. After the front exits to the SE of the basin later this morning, winds will continue to taper off across the basin through Monday morning. A surface ridge from the N will shift E and allow strong SE to S return flow to develop in the western Gulf of Mexico by Tuesday morning. The strong return flow will expand to the eastern Gulf of Mexico on Tuesday night. Another strong cold front could enter the NW Gulf of Mexico by Wednesday morning and introduce another round of gales to the Mexican coast. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Fresh to strong trade winds will continue over the S central Caribbean Sea through Wednesday night and increase to at or near gale force along the immediate coast of Colombia each night through Wednesday. Moderate to locally fresh trade winds will prevail elsewhere. A strong cold front will enter the NW Caribbean Sea later this morning, then move SE and extend from central Cuba to the Gulf of Honduras tonight. The front will weaken but still extend from central-to-SE Cuba to the NW and N central coast of Honduras on Monday night, and then start to weaken and drift N from Cuba westward from Tuesday morning until Tuesday night. Fresh to strong NW to N winds and seas to 8 ft are expected W of the front, from Sunday morning until Monday night. Strong high pres building over the western Atlc will increase the pressure gradient over the basin Tue through Thu. As a result, strong winds will affect almost all of the eastern and central Caribbean during this time frame. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Strong winds are already blowing E of Florida ahead of a strong cold front due to push off the Florida coast by sunrise this morning. The front will then reach from 31N72W to the coast of Cuba near 23N80W tonight, from 30N65W to 26N70W to the coast of Cuba near 21N77W on Monday morning, from 27N65W to the coast of Cuba near 21N77W on Monday night. The front will begin weakening and become stationary on Tuesday afternoon from 23N65W to near the Windward Passage. Minimal gale force winds will be possible on either side of the front N of 28N and W of 65W from this morning through Monday morning. Seas will build to near 20 feet in NW swell behind the front near 31N65W on Tues. Strong winds will develop between the front and 25N on Tue as strong high pressure builds to the N of the front. These winds will persist through Wed night as the strong high slowly shifts E over the western Atlc near 35N. The next cold front should push E from Florida on Thu. $$ .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...
