000 AGXX40 KNHC 080652 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 252 AM EDT Tue May 8 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 weakening stationary front extends from the Florida Keys to 23N90W. The front will dissipate by Tue morning. High pressure measuring 1021 mb is centered S of Louisiana near 27N92W. The high will gradually shift E toward the NE Gulf through Fri, then into the Atlc Sat. A weak thermal trough will move over the eastern Bay of Campeche from the Yucatan during the morning then dissipate during the afternoon each day beginning Wed. Otherwise, a relatively quiet weather pattern will remain in place through the end of the week as deep layer high pressure remains in place over the basin. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A surface trough extending from central Cuba southward to near 13N78W will drift westward through Wed night and dissipate Thu. A broad upper-level trough over the central Caribbean north of 12N will weaken and shift eastward over the eastern Caribbean Tue then into the tropical Atlc Tue night. Scattered showers and isolated thunderstorms over the north central Caribbean will continue through Tue night. Low pressure systems moving E from the United States are weakening the ridge over the western Atlc. This synoptic setup will change on Fri and Sat as the ridge over the western Atlc rebuilds. Strong winds will return to the south central Caribbean as a result. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weak cold front extending from 31N75W to the Florida Keys will slowly move SE and reach from near 31N75W to the central Bahamas to western Cuba Tue morning. The front will reach from near 31N73W to 27N75W to central Cuba Wed then become stationary and gradually weaken through Thu night and dissipate Fri. Fresh to strong S winds N of 27N between 70W and 74W will diminish to gentle to moderate Wed. High pressure ridging extending E to W along 31N Fri through Sat night will generate gentle to moderate E to SE winds over the forecast waters. This high pressure ridge over the western Atlc will combine with a persistent area of slightly lower pressures over the SW Caribbean to support fresh to locally strong winds that will pulse during the afternoon and evening hours each day between the SE Bahamas and the coast of Hispaniola. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
