000 AGXX40 KNHC 061837 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 237 PM EDT Wed Sep 6 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... Tropical Storm Katia centered near 21.7N 95.9W in the SW Gulf off Tampico is getting better organized and is forecast to become a hurricane by early Fri as it meanders over the SW Gulf before making landfall on the coast of Veracruz late Fri. Farther east, Hurricane Irma continues to move WNW toward the Straits of Florida, and is forecast to make a sharp right turn late Sat near the Cay Sal area of the Bahamas toward S Florida. This trend may bring tropical storm force or even hurricane force winds to the eastern portions of Florida Bay. Depending on the eventual track and intensity of Irma as it moves northward up the Florida peninsula, hurricane conditions are possible in the far eastern Gulf early next week. Elsewhere, a cold front is moving into the northern Gulf, and will stall from the Big Bend area of Florida to southern Texas through Fri, before lifting northward ahead of Irma. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Major hurricane Irma has passed the Anegada Passage and is now moving across the Virgin Islands, with storm force winds and large strong swell spilling into NE Carib passages. Trades to be completely disrupted next several days as Irma moves WNW and just N of the Greater Antilles and then veers NW and then N across the Straits of Florida Sat through Sun. TS force winds will be seen on SW coastal waters of Cuba and in Windward Passage as Irma moves past Hispaniola then Cuba. TS Jose to approach Tropical N Atlc waters late Thu into early Fri then turn NW and scare the Leewards as it approaches early Sat. Swell to reach these waters and islands well ahead of Jose. ...SW N ATLANTIC INCLUDING THE BAHAMAS... The main story for the next several days continues to be major Hurricane Irma, now moving across the Virgin Islands and on track to scrape the north coasts of Puerto Rico and Hispaniola through Thu as it approaches the Turks/Caicos and southern Bahamas by Thu afternoon. There is a large area of 12 ft seas to the north of the storm, reaching as far north as 24N per an earlier altimeter satellite pass. No major change in model guidance indicating Irma will continue to the WNW to near the Cay Sal area by late Sat, then take a sharp northward turn into S Florida, then continue northward mainly off the east coast of Florida into early next week. Meanwhile farther east, T.S. Jose is centered 14N45W and is expected to continue to move WNW and pass 55W late Thu into early Fri, then move close the northern Leeward Islands before recurving to the east of the Bahamas. $$ .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...
