...Gulf of Mexico...
A slowing cold front extends from Tampa Bay Florida to 26n90w then becomes stationary to extreme northeast Mexico. The front will stall east to west along 26n late this evening. Remnants of the front will lift north as a warm front on Sat ahead of a second cold front reaching the Texas coast around sunrise on sun preceded by a line of thunderstorms. This second cold front will reach from the Mississippi Delta to the Bay of Campeche on Sun night, from the Florida Big Bend to the Yucatan Peninsula on Mon night, then drift southeast on Tue and finally southeast of the Gulf waters late Wed.
...Caribbean Sea and tropical N Atlantic from 07n to 19n between 55w and 64w...
Atlantic high pressure will maintain fresh to locally strong trades across the south-central Caribbean through early sun. Strong nocturnal trades are then expected to resume on Sun night along the north coast of the South America. Northeast swell currently across the tropical waters east of the leewards will gradually subside through late Sat. A weakening cold front will pass southeast through the Yucatan basin on Tue night, and wash out across the northwest Caribbean during the middle of next week.
...SW N Atlantic including the Bahamas...
A cold front extending southwest from 31n72w to Port Canaveral Florida will reach from Bermuda to South Florida this evening, then stall east to west along 26n on Sat night. Remnants of this front will lift north on sun with near gale force southeast flow developing north of the Bahamas on Mon to the east of a surface low shifting east across the southeast United States. The surface low will move northeast along the Georgia and South Carolina coasts on Tue, and drag a cold front across the northwest waters during the middle of next week. $$
