000 AGXX40 KNHC 190827 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 427 AM EDT Thu Apr 19 2018 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 ridge reaching east to west from southwest Florida to the central coast of Texas will shift eastward ahead of a cold front moving off the coast of Texas currently. Light to moderate E to SE winds are noted over most of the Gulf, with 1 to 3 ft seas in the northeast Gulf and 2 to 4 ft seas elsewhere. Visibility is unrestricted across the Gulf, and no showers or thunderstorms. Fresh to occasionally strong northerly flow will follow the front over the northwest Gulf this morning, but remain generally within 60 nm of the north Texas and southwest Louisiana coasts and diminish this afternoon. The front will reach from the Florida Big Bend area to northern portion of the Mexican state of Tamaulipas this evening. Fresh northerly winds will reinforce the front tonight into Fri. The front will continue south over the eastern Gulf Fri, but stall then drift north over the western Gulf. Fresh to strong easterly winds are possible over the northeast Gulf into Sat as high pressure builds north of the area in the wake of the front. The front will stall and weaken off southwest Florida late Sat into Sun, as another front emerges off the Texas coast late Sat night/early Sun morning. This second weak front will reach from the mouth of the Mississippi River to near Veracruz Mexico by late Sun, and from the Florida Panhandle to the northeast Yucatan peninsula by late Mon, followed by moderate northerly winds. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A trough moving across Puerto Rico into Hispaniola has largely dissipated, although an upper trough over the Windward Passage is supporting isolated showers from central Hispaniola to south of Puerto Rico. Elsewhere, fresh to strong NE to E winds persist off the coastlines of northwest Venezuela to Colombia with 8 to 10 ft seas. Otherwise, moderate winds and seas, with fairly dry conditions persist across the basin. For the forecast, building high pressure north of the area will allow fresh to locally strong trades along the north coast of South America to expand northward over the south central Caribbean into the southwest Caribbean through Fri, then diminish somewhat late this weekend into early next week. Northeast swell will increase east of the Leewards on tonight and Fri, then decay from west to east through Sun. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A dissipating stationary front reaches from 31N61W to 25N71W, bisecting the subtropical ridge along 27N. Moderate to fresh southerly flow is noted off the northeast coast of Florida, between the ridge and lower pressure over the southeast U.S. Seas are generally 3 to 5 ft in open waters. No shower or thunderstorms are noted. Remnants of the stationary front will drift west and become diffuse late today, as a cold front moves off the northeast Florida coast. The front will reach from Bermuda to south Florida by late Fri, then stall from 26N65W to the Straits of Florida late Sat. Remnants of the front will lift north on Sun ahead on another cold front moving east across the southeast United States and entering the northwest waters late Tue. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
