000 AGXX40 KNHC 041745 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 1245 PM EST Sun Nov 4 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 warm front extends across S Florida to 25N82W where it starts to dissipate continuing along 23N87W to 22N91W. Moderate E to SE winds behind the front will become mainly gentle in speeds this afternoon as the front weakens and dissipate by this evening. High pressure centered over the NE CONUS will shift NE to E over the N Atlc waters through Mon. This will allow for winds to become mainly southerly over much of the Gulf by Tue. These winds shift to the southwest over the NW Gulf late Mon night into Tue as a weak cold front moves across the NW and north- central waters. On Wed, the cold front is expected to reach from the NE Gulf to near 26N91W and stationary from there to southern Texas. The front will then lift back to the north as a warm front Thu as yet another cold front advances across Texas and approaches far NW Gulf coast late Thu night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Strong NE winds will funnel through the Windward Passage tonight as high pressure in the NE CONUS shift over north Atlc waters. By Monday, high pressure over the central Atlantic will dissipate, thus allowing for the trades to diminish in the central and eastern Caribbean. Gentle to moderate trades will dominate across the basin the remainder of the forecast period. The combination of a middle level low, upper level divergence and a tropical wave starting to move over the central Caribbean are supporting scattered showers and thunderstorms, some with gusty winds, over much of the northeastern Caribbean. This activity is expected to remain quite active through tonight. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Former stationary front transitioned to a warm front that extends from 31N75W to 27N80W. The front will continue to lift to the N through Mon. Scattered showers and isolated thunderstorms associated with the front will continue across the northwest waters through Mon morning. Fresh to locally strong NE winds along with long period NE swell are over the SE waters. These winds will diminish to mainly moderate winds on Mon and the swell will subside. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
