000 AGXX40 KNHC 291745 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 145 PM EDT Fri Jun 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... Weak high pressure will meander about the E central Gulf through early Tue. Mid to upper level trough moving SSE across the mid Atlc states and SE U.S. has induced a sfc trough across the NE Gulf with very active convection attm. A weak low is forecast to persist across the NE Gulf coastal waters next 2-3 days and drift W to NW with convection likely to prevail to the SE of it. A surface trough will emerge off the Yucatan Peninsula each evening through Tue, and act to enhance nocturnal winds in the SW Gulf. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Modest high pressure ridge across the Atlantic is centered on a 1036 mb high over the N Central Atlc extending SW tot eh NW Bahamas and SE Florida. This producing a moderate pres gradient across the Carib E of 80W and the tropical N Atlc waters, where peak seas are 8 ft. A tropical wave along 67W will move across the Caribbean basin through Sat night. A tropical wave in the central Atlantic along 48W will move into the tropical North Atlantic on Sat, and reach the eastern Caribbean early Sun. Fresh to strong winds across the central Caribbean will gradually diminish Sun through Tue as deep layered troughing moves into the W Atlc and carves away at W periphery of the ridge. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Broad high pressure extending SW across the west-central Atlantic to the NW Bahamas and SE Florida will slowly weaken Sun through Tue as deep layered troughing moves into the W Atlc and carves away at W periphery of the ridge. Generally benign marine conditions are expected across the region through early next week. The northern portion of the next few tropical waves will finally move beyond the SE Bahamas during the next several days as the llvl ridge has built to just beyond 80W. This will allow some SAL to advect NW through the S central Bahamas and eventually to S Florida beginning Sat. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
