203 AGXX40 KNHC 291857 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 257 PM EDT Sun Jul 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 surface ridge extends across the basin, anchored by a 1029 mb high centered over the central Atlantic, supporting 5-10 kt anticyclonic winds over most of the Gulf waters. A stationary front is over S Louisiana and the Florida Panhandle. A pre- frontal trough extends from 30N84W to 28N88W with scattered moderate convection affecting the waters north of 27N and east of 89W. Scattered moderate convection is also over the Florida Peninsula, and a surface trough was analyzed from 23N85W to 26N81W. In addition, scattered showers have reached the SE Bay of Campeche due to a tropical wave extending along 91W. Fair weather prevails elsewhere. Weak high pressure will prevail across the Gulf into next week. A cold front will approach the NW gulf waters Tue, and move across those waters Wed. The front will lift back N to over eastern Texas as a warm front on Wed night, then push eastward over the NW gulf waters as a weakening trough on Thu. Scattered showers and thunderstorms, with possible brief gusty winds and slightly higher seas are expected along and near the front and trough. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Shallow moisture prevails across the basin, and a tropical wave is moving across the central Caribbean. Divergent flow aloft is supporting the convection over western Cuba and adjacent waters north of 20N. In the southwest Caribbean, the Eastern Pacific monsoon trough supports scattered moderate convection over Costa Rica and Panama and waters south of 10N between 76W-83W. Elsewhere, scattered moderate convection is over Hispaniola and Jamaica mostly due to an upper-level low centered over Hispaniola near 19N71W. Strong to near gale-force winds will pulse along the coast of Colombia N of 11N and along the NW coast of Venezuela the next three nights, then will pulse to strong each night thereafter this week. Fresh trade winds will prevail elsewhere across the central Caribbean, with moderate to fresh winds over the eastern Caribbean, and gentle to moderate winds over the western Caribbean. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Diffluent flow between the base of an upper-level trough over the southeast CONUS continues to support scattered to numerous moderate convection north of 25N W of 77W affecting the northern Bahamas and Florida Peninsula. Scattered showers and thunderstorms can be expected to continue over much of the western portion of the area through Wed. High pressure over the west- central Atlantic will prevail across the region through Thu night. Fresh to occasionally strong trade winds are expected just N of Hispaniola through Wed. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
