000 AGXX40 KNHC 241851 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 251 PM EDT Thu May 24 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 broad surface low over the Yucatan peninsula is expected to develop and potentially become a tropical cyclone as it moves slowly northward through Monday. System may evolve by Friday morning into a Central American Gyre structure with a large area of cyclonic winds of fresh breeze to near gale, but lacking a strong inner core characteristic of a tropical cyclone. However, global model guidance is fairly aggressive in spinning the system up to a tropical cyclone before its center reaches the U.S. Gulf coast in three to four days. Strong winds and building seas are likely primarily east of the tropical low center in the NE Gulf. Winds are kept at a peak of 30 kt and seas of 12 ft in the forecast for now. However, an option that may be pursued tonight or tomorrow is to issue oceanic gale warnings before tropical cyclone (or potential tropical cyclone) advisories are issued. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A broad surface low over the Yucatan peninsula will drift northward into the Gulf of Mexico Friday. Fresh to locally strong SE winds and peak seas near 8 ft are expected the NW Caribbean Friday and Saturday as this low potentially develops into a tropical cyclone. High pressure in the central Atlantic will maintain fresh to strong tradewinds in the Caribbean through Saturday with strongest winds along the coast of Colombia before weakening on Sunday and Monday. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Moderate to fresh tradewinds are expected south of 27N through Monday. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
