A cold front currently over the Texas coastal waters will reach from the Mississippi Delta to the western Bay of Campeche this evening, then slow from the Florida Panhandle to the Eastern Bay of Campeche early Sun as a secondary cold front surges S into the northern waters reaching a position from Straits of Florida to near Veracruz, Mexico on Mon night. Remnants of the initial front will weaken to a NW to SE trough that will meander across the SW gulf waters through Wed, while the secondary front lifts N on Tue and Wed. Strong to near gale force northerly post-frontal winds forecast behind todays front, except briefly increasing to minimal gale force along the Mexican coast near 23N97W this morning, with these gale conditions then shifting SW to near Veracruz briefly this evening. Winds should diminish to 20 kt or less across the entire Gulf by late Sun, then increase to a strong breeze behind the secondary front on Sun night and Mon. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Atlc high pressure will maintain strong trades over the Central and SW Caribbean through Wed, with near gale force nocturnal winds near the coast of Colombia. Fresh to strong NE winds are expected through the Windward Passage as well. Large E swell will build seas to 9 ft E of the Lesser Antilles on Mon night, with these swells reaching the E Atlc passages on Tue evening. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A frontal trough extending SW from near Bermuda to along 26N will drift S and gradually dissipate through early Sun as high pressure builds N of the region. This will allow fresh to locally strong NE-E winds near the approaches to the Windward Passage. A cold front will move off the NE Florida coast on Sun evening, and stall from near Bermuda to Central Cuba by Tue. Fresh to strong NW winds will follow the front early Mon, with seas approaching 8 ft.
