000 AGXX40 KNHC 310811 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 311 AM EST Mon Dec 31 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... Platforms across the northwest Gulf are reporting areas of fog, with visibilities varying from 1 nm up to 6 nm. Although there are no reports, fog is likely also in place over the northeast Gulf, where relatively warmer moist air is flowing northward across cooler shelf waters. Dense fog advisories are in effect into the morning for coastal waters from the Florida Big Bend region to southeast Louisiana, as well as over Texas nearshore waters. The areas of fog are reported over much of the northern Gulf, east of a frontal boundary currently stalled from the Sabine Pass to south of Tampico Mexico. The front will drift east through early Tue, then stall again late Tue from Mobile Bay to Tampico, before reversing course and moving north of the area as a warm front through mid week. The front will again change direction and move back into the NW Gulf Thu as an upper disturbance moves into the southern Plains. Strong winds will follow the front as it sweeps SE of the Gulf through early Fri, with minimal gales possible off Veracruz Mexico by late Fri. Winds and seas will diminish starting Fri night as high pressure builds across the Gulf in the wake of the front. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A scatterometer pass from around 02 UTC confirmed gale force winds off the central coast of Colombia. Seas are at least 10 to 13 ft in the area of gales, and 7 to 10 ft elsewhere over the eastern and central Caribbean. No significant convection is noted at this time anywhere across the basin. High pressure north of the area will support strong to near gale force trade winds across the central Caribbean through Fri, pulsing to gale force along the NW coast of Colombia each night through the middle of each morning before diminishing. Locally strong nocturnal trades are forecast across the western Gulf of Honduras and into the Windward Passage through Tue night. Moderate to fresh trades expected elsewhere into Fri. A cold front will move through the Yucatan Channel early Fri, before stalling from central Cuba to northern Belize Fri night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Ridging along 28N will dissipate through the morning as a cold front moves through the central Atlc east of the region. High pressure will build NE of the area in the wake of the front, and the ridge will again become re- established along 28N Tue and Wed. This pattern will continue to support pulses of fresh to strong trade winds north of Haiti near the approaches to the Windward Passage through mid week. A second front will move off the NE Florida coast late Thu, and reach from Bermuda to central Cuba by late Fri. $$ .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...
