000 AGXX40 KNHC 121923 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 223 PM EST Thu Dec 12 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 weakening stationary front extends from south-central Florida to 26N90W, then continues southward to the central Bay of Campeche. The front will begin to lift back to the north while dissipating through Fri. Fresh to strong southerly winds are expected in the western Gulf beginning on Sun and expand eastward to the western half of the central Gulf on Mon as a strong cold front reaches the Texas coast. These winds will diminish to mainly moderate speeds by early Mon as the front reaches the Texas coast. The front is forecast to reach from south-central Louisiana to near Brownsville, Texas late Mon night, from the western Florida panhandle to near 26N94W and to the far western Gulf early Tue and from near Tampa Bay, Florida to near 24N89W and to the south-central Bay of Campeche late Tue night. Model guidance indicates that this front will be followed by strong to near gale force winds over much of the western, northwest and north-central Gulf waters, with the possibility of winds reaching gale force intensity over portions of the western and SW Gulf zones Tue and Tue night. Expect for wave heights to build to large values in the west-central and SW Gulf Tue and Tue night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Winds and seas will gradually diminish across the region through Fri as high pressure in the central Atlantic shifts eastward. Trades across the central Caribbean will increase early next week. Fresh trades along with moderate north to northeast swell are expected across the Tropical N Atlantic waters this upcoming weekend. Scattered to numerous showers and thunderstorms, some with strong gusty winds, may impact the northeast Caribbean and northern Tropical N Atlantic waters through Fri. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weakening stationary front extending from near 31N69W to Stuart, Florida will weaken to a trough on Fri. Fresh to strong northeast winds will continue north of the front through early Fri. Southerly winds will increase Fri night and Sat, ahead of a weak cold front expected to move across the northern waters. High pressure behind this front will quickly slide eastward through early next week allowing for fresh to strong southwest winds to develop over the far northwest waters as the next cold front approaches the southeastern U.S. coast. This front is expected to reach a position from near 31N78W to east-central Florida by late Tue night. The fresh to strong southwest winds are forecast to shift eastward while diminishing to mainly moderate to fresh speeds over the north-central and northeast forecast waters by late Tue night. $$ .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...
