000 AGXX40 KNHC 180830 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 430 AM EDT Mon Sep 18 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... A thermal trough will develop each night over the northwest Yucatan peninsula, and move across the far southwest Gulf through early morning, supporting locally fresh winds and seas briefly reaching 4 to 5 ft. Elsewhere across the Gulf, weak ridging over the lower Mississippi Valley will support gentle to moderate easterly flow across the Gulf through late Fri with seas generally 1 to 3 ft. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Hurricane Maria is about 80 nm NNE of Barbados, moving toward the Leeward Islands, the Virgin Islands and Puerto Rico and the northeast Caribbean through mid week as it strengthens to a hurricane and brings seas in excess of 30 ft. Interests in these areas should monitor the latest bulletins from the National Hurricane Center. Strong winds and swell will push into the Windward Passage late Wed and Thu as Maria moves to the north of Hispaniola. Elsewhere, generally moderate trade winds across the Caribbean will persist through the next several days. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weakening Hurricane Jose is about equidistant between Bermuda and Wilmington NC moving farther to the north. Strong winds and large seas on the southern periphery of Jose still dominate the waters north of 29N, with seas greater than 8 ft north of 27N persisting through late Tue. Beyond that, winds and seas rapidly diminish through mid week north of 25N. Attention turns to the next hurricane, Maria, forecast to bring to the Atlc waters between the Leeward Islands and 22N tonight into early Tue. The forecast continues is for hurricane conditions in the Atlc coastal waters of the Virgin Islands and Puerto Rico starting late Tue, then continuing WNW with hurricane conditions possible for the Turks/Caicos and southern Bahamas by early Thu. Afterward, the forecast calls for Maria to turn toward the north into a weakness in the subtropical ridge created by the slow departure of Jose. This forecast scenario takes Maria on a more northward track so it stays to the east of the central and northern Bahamas. Given track and intensity errors increase farther out into the future, marine interests throughout the region should continue monitoring the latest bulletins issued by the National Hurricane Center on Hurricane Maria. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
