000 AGXX40 KNHC 031807 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 107 PM EST Thu Jan 3 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 frontal system extends from the Florida panhandle to low pressure south of the Texas and Louisiana border to central Mexico. Patchy rain is occurring N of the front within 120 nm of the coasts of Texas and Louisiana between 90W and 95W. Ridging extending WSW from central Florida to near Veracruz Mexico is maintaining fair weather over the remainder of the Gulf to the SE of the front. Reinforcing cold air will force the front eastward the next few days, extending from the Florida panhandle to the Isthmus of Tehuantepec tonight, from central Florida to Yucatan peninsula Fri night, then sweep SE of the Gulf on Sat. Fresh to strong winds will follow the front across the western Gulf tonight and Fri. Winds and seas will diminish Fri night and Sat west of the front. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... The tail end of an old stationary front passes from the Atlantic Ocean across Guadeloupe to S of Hispaniola near 17N71W. Shallow clouds and isolated showers are found along and up to 60 nm N of this boundary. Otherwise, deep-layer high pressure is restricting deep convection over the remainder of the basin. Broad high pressure across the west-central Atlantic will maintain fresh to strong winds across much of the Caribbean through Fri, with near gale-force winds possible at night near the Colombia coast. A cold front will stall and weaken in the NW Caribbean this weekend. Winds and seas will diminish slightly over the weekend as the high to the north weakens and shifts eastward. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Broad high pressure across the west-central Atlantic will weaken and shift eastward through the weekend. A cold front moving off the coast of NE Florida Fri night will reach from Bermuda to Cuba Sat night, then flatten out to weaken along 23N Sun and Mon. Strong to near gale-force SW to W winds are expected N of 28N ahead of and behind this frontal system Fri afternoon through early Sun, with seas building to 8 to 13 ft. High pressure will build north of the region early next week with improving marine conditions. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
