000 AGXX40 KNHC 041025 AAA MIMATS Marine Weather Discussion...UPDATED NWS National Hurricane Center Miami FL 525 AM EST Sun Nov 4 2018 Updated Caribbean Sea and Tropical N Atlantic 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 stationary front extends from the Straits of Florida to 23N88W and to the eastern Bay of Campeche. Moderate to fresh east to southeast winds behind the front will become gentle to moderate in speeds this afternoon as the front weakens and dissipate by this evening. High pressure elsewhere over the area will shift eastward through Tue. The moderate to fresh northeast winds become mainly southerly, gentle to moderate in speeds, on Mon over much of the Gulf. 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 the far NW Gulf coast late Thu night. There are some timing differences with the global models in depicting the front emerging off the Texas coast late in the upcoming week. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...Updated to include mention of unsettled weather over the northeastern Caribbean Sea High pressure north of the area over the central Atlantic will shift eastward through Mon. Strong trades along the coast of Colombia will diminish early Sun. Strong trades will pulse within about 60 nm south of central Hispaniola through tonight before diminishing Mon. Elsewhere, trades will weaken Tue through Thu. Scattered showers and thunderstorms over the Yucatan Channel and near northwestern Cuba will move northward through tonight. Unsettled weather in the form of numerous showers and scattered thunderstorms continues over the northeastern Caribbean Sea, covering the area north of 15N and between 63W and 70W to include Puerto Rico and the Virgin Islands. Some of the shower and thunderstorm activity may contain strong gusty winds and frequent lightning strikes. This activity is being triggered by an upper-level trough, with its axis noted on water vapor imagery to be roughly along 68W. A jet stream branch accompanied by strong southwest winds lies to the E of this trough. With an already present very moist and unstable environment over the eastern Caribbean, the presence of jet stream-related dynamics that favor upper-level divergence is leading to plenty of atmospheric instability and very favorable conditions for showers and thunderstorms to develop over the aforementioned waters of the northeastern Caribbean. Expect for the activity to last through much of tonight and possibly into Mon. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A stationary front extending from near 31N74W to the central Bahamas and to the Straits of Florida will dissipate by this evening. Its remnants will lift to the N as a warm front through Mon. Scattered showers and isolated thunderstorms along and northwest of the front will continue through tonight. Northeast winds of fresh intensity along with long period NE swell are over the SE waters. These winds will diminish to mainly moderate winds on Mon. The swell will slowly subside through Mon. High pressure will the dominate weather feature during the upcoming week. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
