000 AGXX40 KNHC 060800 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 400 AM EDT Sat Apr 6 2019 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... High pressure extends from the Atlantic to the NE Gulf waters. A moist southeast wind flow south of the ridge will support areas to patches of fog, some dense, over much of the northern Gulf into early Sun. The southeast wind flow will begin to increase over the western Gulf today as the high pressure builds some to the west and the Yucatan Peninsula trough shifts westward to the SW Gulf. A cold front, preceded by scattered showers and thunderstorms, is expected to approach the Texas coast late Sun night and move over the far NW Gulf early on Mon. It will move across the basin through early next week while weakening to a trough as it reaches the far southeastern Gulf by late on Wed. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure north of the region will support fresh to strong trade winds across the southeast and south-central Caribbean through early next week, reaching near gale force off Colombia mainly at night. The pattern will also support fresh to strong winds through the Gulf of Honduras into early next week. Long- period northeast swell will propagate through the waters east of the Leeward Islands through early next week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Atmospheric moisture has increased over much of the basin during the past 24 to 48 hours as a mid to upper-level trough advances eastward across the western part of the area. Latest satellite imagery and current NWS mosaic radar displays show scattered showers and thunderstorms within 30 nm either side of a line from 28N80W to 29N76W to north of the area at 31N74W. A surface trough is also enhancing this activity. This activity is forecast to continue to eastward through this afternoon while weakening as the the mid and upper-level trough dampen out and is replaced by ridging. The ridging at the surface will continue to hold through Tue, then begin to shift eastward into Wed in response to low pressure that is forecast to track northeastward from the lower Mississippi Valley to the southern Appalachians and Tennessee Valley by Monday evening and to the Mid-Atlantic coast by late Tue night. A cold front associated with this low is expected to emerge off the southeastern U.S. coast late on Tue, and move across the western central forecast waters through Wed night. The latest model guidance concurs that the front will be preceded by mainly fresh southwest winds and followed by gentle to moderate west to northwest winds. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
