000 AGXX40 KNHC 221746 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 1246 PM EST Sun Dec 22 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 nearly stationary frontal boundary extends from 1011 mb low pressure south of Mobile Bay toward the Yucatan peninsula. This pattern is supporting winds to gale force and building seas over the northeast Gulf and off Veracruz in the southwest Gulf. Clusters of thunderstorms ahead of the front are bringing gusty winds and lower visibilities due to locally heavy rainfall to portions of the eastern Gulf today. Winds and seas will diminish as the trailing cold front sweeps southeast of the Gulf tonight and the low lifts northeast toward the Georgia coast through late Mon. Weak high pressure sets up in the wake of the front over the western Gulf through mid week. Looking ahead, winds may increase over the northeast Gulf by late Thu as a weak front approaches the region. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A cold front entering the southeast Gulf of Mexico will move through the Yucatan Channel and into the far northwest Caribbean later today. The front will reach from the central Cuba to the Gulf of Honduras by early Mon from eastern Cuba to northeast Nicaragua by early Tue, before stalling and weakening from Windward Passage to Providencia Island through mid week. Fresh to strong winds will follow the front over the western Caribbean. Elsewhere, the front and its parent low pressure will shift into the western Atlantic to the north of the area, displacing the subtropical ridge and allowing moderate trade winds by mid to late in the week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Deepening low pressure currently over the north central Gulf of Mexico will move toward the Georgia coast by late Mon, with a trailing cold front moving off the east coast of Florida. SE winds will increase to gale force by late today off northeast Florida ahead of the approaching low and front. The front will continue to sweep eastward, reaching from 31N72W to western Cuba by early Tue as the low slowly moves toward 31N76W. The low pressure will weaken little as moves toward 29N65W by early Wed, with the front extending to the Windward Passage. Looking ahead, winds and seas diminish across the region after late Wed as the low and front move farther east and weaken. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ015...NE GULF N OF 25N E OF 87W...
