000 AGXX40 KNHC 131823 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 223 PM EDT Tue Jun 13 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... The showers and thunderstorms over the far SW Gulf that were associated with T.S. Calvin which made landfall last night over the Pacific coast of Mexico have dissipated. Only weak surface troughing remains along the Veracruz coast of Mexico. Buoy 42055 is only reporting 15 kt winds and 4 ft seas. Otherwise, satellite-derived wind data and buoy reports indicate moderate to occasionally fresh E to SE winds and 2 to 5 ft seas prevail over the Gulf. Weak ridging over the western Atlantic and SE United States will continue to maintain gentle to moderate breezes and slight seas over the eastern Gulf, and moderate to fresh breezes with 3 to 5 ft seas over the western Gulf, subsiding through Friday. Looking ahead, winds will increase over the SW Gulf by late Saturday ahead of a low pressure area expected to approach the region through northern Central America. Winds in the vicinity of the Yucatan Peninsula could become strong by Sunday night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Moderate to fresh E to ESE winds prevail across the Caribbean, except for the portion of the Caribbean closest top the Monsoon Trough to the south of 10N. The strongest winds of around 20 kt cover the central Caribbean, and are associated with a tropical wave passing S of Hispaniola. This wave will cross the SW Caribbean through mid week. Seas are 6 to 8 ft in the south central Caribbean and 4 to 6 ft elsewhere east of 80W. Fresh winds continue to pulse to strong speeds at night over the Gulf of Honduras with seas peaking around 7 ft, but moderate to fresh winds persist elsewhere over the NW Caribbean. Winds and seas will diminish farther east into Thursday as the high pressure ridge to the north is weakened by a cold front sagging southward. By Friday, developing low pressure near or over Central America will slowly move NW toward southern Mexico. This will cause southeast winds to increase and seas to build over the northwest Caribbean through Sunday. High pressure rebuilding over the western Atlantic over the weekend will generate moderate to fresh trade winds and 5 to 7 ft seas over much of the Central and Eastern Caribbean. Moderate to fresh trade winds will persist across the tropical north Atlantic waters west of 55W through Sunday. Long period N swell will maintain seas of 6 to 8 ft through Wednesday, then seas will subside slightly thereafter. ...SW N ATLANTIC INCLUDING THE BAHAMAS... The subtropical ridge will extend westward through Wed along 32N, then slowly sink southward to near 28N by late week. The ridge will maintain gentle to moderate winds and slight seas north of 22N, and moderate to fresh trade winds south of 22N. winds will pulse to locally strong each night north of Hispaniola and near the approaches to the Windward Passage through Friday night. The coverage of strong winds N of Hispaniola could become greater on Sat and Sun nights as the high pressure ridge to the north rebuilds. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
