000 AGXX40 KNHC 210750 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 350 AM EDT Mon Aug 21 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... A few showers and thunderstorms are active across the SE Gulf on the NE side of an upper low centered over the central Gulf near 26N89W. An associated surface trough is analyzed from SE Florida to western Cuba. This weather will move with the upper low as it tracks WNW toward the Texas coast through mid week, while winds will increase to fresh in the SE Gulf through the Straits of Florida in the wake of the surface trough through the early part of the week. Meanwhile the remnants of Harvey in the Caribbean will move across the Yucatan peninsula and may emerge into the far SW Gulf/Bay of Campeche Wed bringing increasing winds and seas along with active convection, possibly re- developing into a tropical cyclone as it moves NNW toward NE Mexico through late week. Elsewhere, weak ridging will persist across the northern Gulf or along the northern coast, maintaining light to gentle winds and slight seas. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... The remnants of former tropical cyclone Harvey are centered over the central Caribbean between Grand Cayman Island and central Panama. The convection remains disorganized over eastern Honduras well to the west of the poorly low level center. Along with scattered thunderstorms, Harvey is accompanied by fresh to strong winds and seas of 8 to 10 ft on its northern periphery as it continues to move WNW through the northwest Caribbean through early Tue, with a medium chance of re-developing into a tropical cyclone. Interests in Central America should continue to monitor http://hurricanes.gov for the latest on this area. A broad tropical wave is associated withe remnant low of Harvey, between central Cuba and central Panama. A 02 UTC scatterometer pass indicated strong eastern winds between Jamaica and eastern Cuba in the wake of the tropical wave. Moderate to fresh easterly trade winds persist elsewhere. Winds will pulse to fresh to strong in the S central Caribbean late Wed night through the end of the week as the pressure gradient tightens across that area. Another tropical wave will pass 55W Tue, enter the eastern Caribbean Wed, then cross the central Caribbean through late in the week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Scattered showers and thunderstorms are noted east of the central Bahamas associated with a trough reaching from central Hispaniola northward along 72W to 25N. An area of fresh winds and seas of 8 to 9 ft also accompany the trough as it moves west toward the central and southern Bahamas through mid week. Meanwhile, ridging extends from E to W along 30N. The ridge will lift northward as the trough continues to progress to the W, reaching the southern Bahamas and Turks/Caicos late tonight. Weak ridging will build across the area through midweek with fairly tranquil marine conditions expected basin-wide. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
