The earlier weakening stationary front has dissipated. Both buoy and altimeter data show seas in the 4-5 ft range between 22N and a line from just Galveston to the NW Cuba, and lower seas of 1-2 ft north of this same line. High pres ridging extending from the Atlantic westward to across the northern gulf will begin to weaken and slide eastward on Mon night in response to a cold front that will move across Texas. This cold front will reach the Texas coast late Tue night, and move across the NW gulf during Wed morning, reach from N-central Florida to near 25N90W and to near Veracruz Mexico by Wed evening, then weaken across the southern gulf waters on Thu and dissipate Thu night. Fresh to strong NE winds will follow in behind the front becoming mainly moderate to fresh NE to E winds on Thu and Thu night as high pres ridging over the northern gulf slides eastward. Return southerly flow of SE to S moderate to fresh winds develop over the western gulf from late Thu night through Fri night as the ridging continues to shift eastward. A thermal trough will develop over the Yucatan Peninsula during the afternoons, drift west across the eastern Bay of Campeche during the overnight hours, and dissipate over the SW gulf by late each morning through Fri followed by fresh to strong E to SE winds on Mon and Tue. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Strong NE winds will pulse at night along and near the northwest coast of Colombia through Wed. A surface trough approaching the Lesser Antilles will move across those islands tonight into early Mon accompanied by scattered showers and isolated thunderstorms. It will continue to move westward across the eastern Caribbean Mon through Tue night before become diffuse south of Hispaniola on Wed. Strong east winds will develop across the Gulf of Honduras on Tue night and diminish on Wed. Otherwise, gentle to moderate trades are forecast elsewhere through Fri night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... The earlier dissipating stationary front along 80W north of 27N has become an inverted trough. Buoy reports indicate a sharp wind sharp wind across the trough from N to NE moderate winds to its west to moderate E to SE winds to its east. Buoy and altimeter data show seas in the range of 4-6 ft east of the Bahamas and 1-3 ft west of the Bahamas except in the Straits of Florida where seas are in the 3-5 ft range. The trough will lift north tonight and dissipate. A trough just southeast of the area will move across the eastern waters tonight through early Mon, and reach the SE Bahamas Mon night before becoming diffuse. Another trough will move across the eastern waters Mon night through Tue night, and across the SE Bahamas Wed and Wed night while weakening. These troughs may be accompanied by scattered showers and isolated thunderstorms. A high pres ridge extending from near Bermuda to Cape Canaveral Florida will change little through Wed, then retreat eastward allowing for a cold front to enter the far northwest waters on Wed evening. The front will extend from near 31N72W to 25N71W to NW Cuba Thu afternoon, from near Bermuda to east-central Cuba Thu night and weaken over the eastern waters on Fri. Strong N to NE winds will follow in behind the front, with seas building to around 10 ft. These winds then shift to N-central waters on Thu night into Fri and diminish to fresh winds over zone AMZ115 during Fri. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
