971 AGXX40 KNHC 291740 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 140 PM EDT Wed Aug 29 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 weak ridge extending from high SW of Bermuda WNW across gulf coast states will dominate the Gulf waters into the weekend and support gentle to moderate winds. A surface trough will develop each evening over the Yucatan Peninsula before moving W and offshore into the SW Gulf overnight. A surge of moderate to fresh NE to E winds will accompany this trough each night. Strong llvl jet associated with tropical wave entering E Carib attm is expected to move across S Florida and WNW across E Carib early next week. Jet will have weakened by that time but should still initiate convection. 00Z EC still developed TC across NW Bahamas with this wave but see nothing more than weak troffing with any of the other global models. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Fresh to strong winds will prevail in the south- central Caribbean today before diminishing tonight through Sat as W Atlc high remains just SW of Bermuda...and tropical wave with sharp axis moves across the basin and diminishes pres gradient. Very active weather expected with this wave as strong llvl jet accompanies wave and SAL-moisture boundary ahead of wave will likely yield squalls. Gentle to moderate winds will prevail elsewhere. ...SW N ATLANTIC INCLUDING THE BAHAMAS... High pres will remain centered SW of Bermuda through the forecast period, supporting moderate to fresh winds S of 24N and gentle to moderate winds N of 24N. Winds will pulse to fresh to strong just N of Hispaniola, including approach to the Windward Passage, during the evening and overnight hours through Sun. A tropical wave moving into the NE Caribbean and adjacent Atlc today will produce active weather as it moves westward across the Lesser Antilles and Bahamas through Mon. 00Z EC still only model suggesting any cyclogenisis across NW Bahamas late Mon from this wave, and a few Canadian ensemble members. Confidence thus low. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
