000 AGXX40 KNHC 151942 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 242 PM EST Mon Feb 15 2021 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... Low pressure of 1008 mb is centered near 28N92W, with a cold front extending from it to 24N93W and to Veracruz, Mexico. A warm front extends from the low to 29N90W and to 28N88W, where it transitions to a cold front to weak low pressure of 1013 mb near 29N84W. A very tight gradient between strong high building southward over the western Gulf and the cold front associated to the low pressure near 28N92W is resulting in gale force northerly winds over the western Gulf waters as well as over the western part of the north-central waters. Along with these winds, seas have build to large values over the NW and west-central Gulf areas. The gale force winds will diminish during the afternoon as the 1008 mb low lifts north of the area, with the trailing cold front extending from the western Florida panhandle to near 25N89W, and to inland the northwest part of the Yucatan Peninsula. The cold front will weaken as it reaches the far southeastern Gulf Tue, where it is expected to become stationary, before lifting back north as a warm front Tue night and Wed. Another low pressure system will track east-northeastward across the NW Gulf on Wed and Wed night dragging a strong cold front across the western Gulf. This cold front is expected to reach from near Apalachicola, Florida to the eastern Bay of Campeche on Thu, and exit the Gulf on Fri. Gale conditions will be possible behind this front off Veracruz on Thu. Strong to near gale force southerly winds are possible ahead of this front. Fresh to strong winds northeast winds will be over the southeastern Gulf Sat and Sat night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure north of the area will maintain fresh to strong trade winds across the central and eastern Caribbean through Thu. Winds off Colombia will pulse to gale force at night through Wed. Southeast winds will increase in the Gulf of Honduras from Wed night into Thu as a strong cold front approaches from the Gulf of Mexico. The cold front is expected to move across western Cuba, the Yucatan Channel and the northeast part of the Yucatan Peninsula early on Fri and over the northwestern Caribbean during the rest of Fri and through Sat as it slows down and becomes stationary into Sat night. It will be followed by strong northerly winds. Large north swell will continue to affect the tropical N Atlantic waters through Thu, then begin to subside Thu night through Sat night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... High pressure over the region will support fresh to strong winds north of Hispaniola through Thu night. Fresh to strong southerly winds will develop east of northern Florida tonight through Tue ahead of a cold front that will move east of Florida on Tue. The front will become stationary Tue night from near 31N74W to West Palm Beach, Florida, then lift northward as a warm front Wed and dissipate Wed night. Scattered thunderstorms, some possibly strong with gusty winds, along a squall line are expected ahead of the front tonight. Winds will increase over the western waters, including the waters between the southeastern Bahamas and Hispaniola beginning on Thu as a cold front moves across the Gulf of Mexico. The front will move east of Florida early on Fri, and extend from near 31N71W to the central Bahamas and to central Cuba late on Fri and from near 28N65W to near Windward Passage Sat and Sat night. Fresh to strong northerly winds will follow this front. $$ .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...
