000 AGXX40 KNHC 300626 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 226 AM EDT Mon Oct 30 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... Moderate to fresh winds and seas of 8 to 10 ft in northerly swell persist across mainly the SE and far SW Gulf in the wake of a cold front that moved through the area yesterday. 1017 mb high pressure centered over the NW Gulf will shift E toward the Carolinas through early in the week, allowing winds to diminish over the eastern Gulf, but also supporting fresh return flow across the western Gulf through mid week. The ridge will weaken through late in the week allowing winds and seas over the NW Gulf to subside. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A cold front front reaching from central Cuba to the Gulf of Honduras will weaken as it drifts farther south, eventually stalling as a shear line by Mon then dissipating from eastern Cuba to eastern Honduras by Tue. Fresh winds and seas to 8 ft are pushing through the Yucatan Channel, and moderate to fresh NE winds will persist over the NW Caribbean through mid week. Elsewhere a weak pressure pattern remains in place through maintaining gentle to moderate breezes and 2 to 4 ft seas through late week, except for occasional overnight fresh winds off Colombia. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Strong winds persist off NE Florida and N of the Bahamas following a cold front reaching from 31N73W to central Cuba. Altimeter satellite and buoy data show seas are 8 to 14 ft. Winds will diminish through the morning as deep low pressure north of the area lifts out and high pressure builds eastward. The front will stall from 31N64W to the vicinity of the Windward Passage Mon night. The large seas in mixed swell N of 27N will quickly subside once the front stalls with winds diminishing to 20 kt or less. The front will then retrograde westward as a remnant trough through mid week, becoming diffuse if not dissipating by the end of the week. Much more tranquil marine conditions are expected through the end of the week. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
