000 AGXX40 KNHC 282032 AAA MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 432 PM EDT Mon Sep 28 2020 updated Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W section 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 strong cold front extends from southwestern Lousiana to inland Texas near Brownsville. The front will reach the southeastern Gulf waters Wed and the Straits of Florida by Wed evening. In the wake of the front, strong northerly winds are expected in the western half of the basin, with gale force winds expected west of 95W on Tue. A secondary front will drop southward to the northern Gulf early on Fri and reach the far southwestern Gulf by Fri evening. Strong high pressure will build in behind this front. The pressure gradient between the front and a tropical wave that will approach the western Caribbean is expected to freshen the northeast winds over most of the southeastern Gulf by the end of the week. These winds may reach strong speeds on Sat and build the seas to around a maximum value of 10 ft in that part of the Gulf on Sat and Sat night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...Updated Moderate to fresh trade winds over the central Caribbean will increase to fresh to strong speeds by mid-week. Moderate winds will continue elsewhere, except for gentle winds over the northwestern Caribbean. A tropical wave, currently located along 67W, will continue moving westward across the basin through the end of the week and into the weekend accompanied by active weather and enhanced winds along with building seas. This feature is expected to become part of a broad low pressure area over the western Caribbean in a few days. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Weak high pressure over the western Atlantic is maintaining generally gentle to moderate winds across the area. The high pressure will begin retreat eastward through Wed in response to a cold front that will be moving across the southeastern U.S. This cold front will reach the southeastern U.S. coast Tue night and move over the northwest part of the area through Wed. The front will begin to weaken as it reaches from near 31N74W to South Florida by Wed night and become stationary from 31N73W to the Straits of Florida by late Thu through Fri night, then diffuse Sat. Scattered showers and thunderstorms are expected ahead of the cold front. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ017...W CENTRAL GULF FROM 22N TO 26N W OF 94W...
