000 AGXX40 KNHC 010758 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 358 AM EDT Sat Apr 1 2017 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... Scattered showers and thunderstorms over the eastern Gulf have dissipated along a weakening and stalled frontal boundary reaching from near Fort Myers Florida to 24N90W. As this boundary decays, a warm front will form over the northern Gulf related to deepening low pressure west Texas, with increasing southerly flow across mainly the central Gulf today and seas building to 8 to 10 ft. The warm front will lift north through tonight as the low pressure shifts into the Mississippi Valley. The strong southerly winds will be relegated to mainly the northeast Gulf Sunday into Monday a trailing cold front will move off the Texas coast, and reaches from near Mobile Bay to the northwest Yucatan peninsula. Southerly winds may reach near gale force Saturday into Monday, with near gale force possible off Veracruz as well by early Monday. Winds seas will diminish starting late Monday across the Gulf as the cold front shifts east of the area and high pressure builds across the basin. Looking ahead, fresh to strong northerly flow will follow another cold front moving off the Texas coast by Wednesday, reaching at least near gale force off Veracruz by late Wednesday night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Relatively weak high pressure north of the area has been maintaining gentle to moderate trade winds for the most part across the basin for the past couple of days. Winds and seas are starting to increase across the area as the pattern north of the area becomes more amplified with a series of progressive low pressure systems, allowing with fresh to strong winds pulsing overnight off Colombia and the Gulf of Honduras through early next week. By mid week, strong ridging over the western Atlantic will support a large area of fresh to strong trade winds across the southeast and south central Caribbean. Meanwhile longer period northerly swell reaching 8 to 10 ft will reach the Leeward Islands by late Saturday, then propagate southward along the Atlantic exposures of the Windward Islands through late Sunday. The swell is generated by a powerful low pressure system in the north central Atlantic, and will gradually decay below 8 ft over the tropical north Atlantic through Tuesday. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Fresh to strong southerly flow along with a few showers and thunderstorms are evident north of 30N west of 75W ahead of a cold front reaching from 31N77W to Melbourne Florida. The front will continue eastward and reach from Bermuda to southeast Florida by late today. The northern portion of the front will shift east of the area Sunday, as the southern portion stalls along roughly 27N today, and becomes diffuse Sunday. Meanwhile northerly swell to 9 ft will propagate southward over the region east of 70W and north of 27N through early next week. The pattern will repeat starting late Sunday as southerly flow again increases off northeast Florida ahead of a second cold front approaching from the west. Looking ahead, this front will make little progress east and lift northward again by mid week ahead of a third strong front moving eastward across the Gulf of Mexico. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
