000 AGXX40 KNHC 150800 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 400 AM EDT Fri Mar 15 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... As of 06Z, a reinforcing cold front extends from southeastern Louisiana to 25N95W and to inland Mexico near Tuxpan. Strong high pressure is building southeastward over the NW gulf waters behind this front, with the gradient between it and the front bringing moderate to strong north to northeast winds over those waters. Post-frontal isolated to scattered showers and thunderstorms as noted on mosaic NWS radar are mainly occurring in a line from near 27N96W northeastward to inland southwestern Louisiana near Grand Isle. The cold front will reach from near from near Panama City, Florida to the central gulf by this afternoon, where it will transition to a stationary front continuing southwestward to the Bay of Campeche. As cold air advection settles in behind the front, expect for mixing of stronger winds aloft to the surface to bring strong to near gale force northerly winds behind the front. Winds are forecast to increase to gale force this evening evening near Veracruz, Mexico and possibly in Tampico adjacent waters. The cold front will begin to slow down as it moves across the eastern Gulf waters Fri night into Sat, becoming stationary from near Fort Myers, Florida to near 23N87W and to the eastern Bay of Campeche from Sat and through Sun night before it is nudged southward as a cold front on Mon in response to a new area of strong high pressure builds southeastward from the northern Plains to the eastern and central Gulf at that time. On Mon, the front is expected to become stationary again as it reaches the lower part of the Straits of Florida or possibly over northern Cuba and extend west-southwestward to near or over the northern and western sections of the Yucatan Peninsula and to the eastern Bay of Campeche area and continue through Tue. Low pressure may form along the western part of over the eastern Bay of Campeche near the northwest part of the Yucatan Peninsula late on Mon night and track in a general east-northeast direction along the frontal boundary through Tue. The gradient between it and the aforementioned strong high pressure that will build southeastward over much of the Gulf early next week, should result in an increase of winds along with building seas over much of the east-central and southeastern Gulf waters early next week. A remnant trough from the front will set up in northwest to southeast direction over the SW Gulf late on Sun, with strong northwest winds to its southwest over the SW Gulf and strong northeast winds to its NE over much of the central Gulf. This trough will begin to weaken late Mon and through Tue allowing for these winds to diminish. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure to the north of the area will support fresh to strong trades over much of the central Caribbean through Tue. The tight pressure gradient between it and low pressure over northwestern Colombia has induced gale force northeast winds within 90 nm of the coast of Colombia. These winds will diminish to near gale force just after 12Z this morning, then continue at near gale force speeds through early next week. Fresh to strong east winds are over the Gulf of Venezuela and Belize offshore waters. These winds will diminish to fresh speeds this afternoon. Winds will diminish further to gentle to moderate speeds over the Belize offshore waters on Sat and change little through early next week. Winds will pulse back up to strong speeds over the Gulf of Venezuela at night beginning on Sun and through early next week. Moderate to fresh trades will continue across the remainder of the area through early next week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weakening stationary front along 22N and east of the SE Bahamas will begin to dissipate this afternoon. High pressure north of the front will shift east-southeastward through the weekend in response to the next cold front that will move off the southeast Georgia and northeast Florida coasts tonight. This cold front is forecast to reach from near 31N77W to near Stuart, Florida and continues a stationary front to the eastern Gulf of Mexico by early on Sat afternoon, from near 31N72W to 29N76W and stationary to near West Palm Beach by late Sat night, from near Bermuda to near 29N74W and stationary to southern Florida by early Sun, from near 31N65W to 29N69W and stationary to the NW Bahamas and to southern Florida by early Mon afternoon and stationary from near 29N65W to 27N74W and to the central Bahamas and to the Straits of Florida or over Cuba on Tue. High pressure north of the front will slide eastward early next week as a frontal wave or low pressure rides northeastward along the front. Expect for the combination of the frontal wave or low pressure with the high pressure to lead to fresh to strong northeast winds and building seas to impact much of the central and western waters early next week. Stay in tuned to future forecasts that will provide details on these expected marine conditions. $$ .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...
