000 AGXX40 KNHC 061003 AAA MIMATS Marine Weather Discussion...Updated NWS National Hurricane Center Miami FL 503 AM EST Wed Feb 06 2019 Updated Gulf of Mexico section 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...Updated High pressure centered over northern Florida will shift eastward over the western Atlc by Thu as a strong cold front moves across eastern Texas. This front will move over the NW Gulf Thu night, quickly reaching from Florida Big Bend to near Veracruz, Mexico by Fri evening, then weaken as it reaches from Sarasota, Florida to near 26N90W and becomes stationary to the SW Gulf Sat. Very strong high pressure will build across the area in the wake of the front, with the resultant tight pressure gradient bringing strong to near gale force northerly winds over the W central and SW Gulf Fri through Sat. Scattered showers and isolated thunderstorms will be possible with this cold front. Winds diminish and seas subside mainly over the western and central Gulf on Sun as the strong high pressure over the area shifts eastward to the western Atlantic and the front becomes diffused. Strong east to southeast winds will pulse at night near the northwest coast of the Yucatan Peninsula through Sat. Areas of dense fog reducing visibility to 1 nm or less are evident in satellite imagery and in surface/marine observations to be confined along most of the coastal sections of the Gulf north of about 27N early this morning. The fog is expected to dissipate, for the most part, by late this morning or early afternoon. However, it may linger as patchy fog in some locations beyond this time. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Fresh to strong winds are over the S central Caribbean, with the exception of minimal gale force northeast winds within 60 nm of the coast of Colombia as noted by a recent observation from ship with call sign "9HA4330" located at 12N75W at 06Z this morning. As low pressure over Colombia deepens some over the next few days, and while at the same time high pressure builds over the western Atlantic, the resultant tightening of the pressure gradient will be conducive for these gale force winds to again pulse at night through Sun. Otherwise, mainly moderate to locally fresh winds will continue across the basin through Thu night, increasing to fresh to strong speeds and expanding in coverage beginning on Fri to include the Windward Passage and the waters in the lee of Cuba as well. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A cold front extends from a triple point north of the area at 35N57W south-southwest to 31N60W and to 26N65W, where it becomes stationary to just north of the coast of Hispaniola. The front will exit the forecast waters N of about 25N late this afternoon or evening, with its southern portion to extend southwestward as a stationary front to near the northeast coast of the Dominican Republic as high pressure behind it builds southward. Moderate to fresh northwest to north winds west of the front to near 74W will become northeast winds at gentle to moderate speeds by early this evening. Seas to 8 ft in mixed northeast and northwest swell north of 30N between 55W and 59W will subside to less than 8 ft later this morning. The next cold front will move over the far northwest waters on Fri night then reach from near 31N67W to 28N76W and become stationary to inland Florida near Cape Canaveral on Sat. Very strong high pressure behind this front will lead to strong northeast to east winds along with building seas, likely to peak to around 13 ft, over the waters to the N and NE of the Bahamas late on Sat and Sat night. Seas north and northeast of the Bahamas will slowly subside on Sun as the front washes out in the high pressure surrounding environment. $$ .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...
