Please see Special Features section above for information on a Gale Warning in effect for areas offshore Veracruz, Mexico. Moderate to fresh southerly winds continue over the Gulf ahead of an incoming cold front, with locally strong breezes in the southeast part of the basin. The southerly wind flow is bringing warm moist air northward over the cooler shelf waters of the northern Gulf, resulting in fog. Dense fog, with visibility below 1 nm, is being reported within 60 to 90 miles of the Texas coast. An elongated surface trough extends along the eastern coast of Mexico to the central Bay of Campeche, however, no significant weather is associated with this feature. Seas are 3 to 5 ft, except within the central Gulf seas are up to 7 ft. For the forecast, the dense fog along the Texas coast is forecast to persist until early this afternoon. The fresh to locally strong S winds in the southeast Gulf will diminish tonight. The cold front will move off the Texas coast this afternoon. Strong N winds and building seas will follow the front, which will reach from the Florida Big Bend to the central Bay of Campeche by Thu morning. Gales will develop on Thu morning offshore Veracruz, Mexico, and continue through the evening. The cold front will move SE and exit the basin by Fri morning. High pressure will move E across the northern Gulf Fri through the weekend. CARIBBEAN SEA... The gradient between low pressure over Colombia and high pressure north of the area is maintaining moderate to fresh E winds across the basin, noted in scatterometer imagery. Strong winds are occurring within 60 nm offshore Colombia and in the Gulf of Honduras, south of 18N. Seas are 4 to 6 ft in the Caribbean, except 6 to 8 ft in the aforementioned areas of strong winds. With generally dry air aloft, no significant convection is occurring. For the forecast, high pressure north of the area will continue to support fresh to strong winds in the south-central Caribbean near the coast of Colombia into tonight. Fresh to strong winds in the Gulf of Honduras will continue into Thu. Moderate to fresh winds will prevail elsewhere. A cold front will reach the Yucatan Channel by Fri morning, then move through the NW Caribbean this weekend. ATLANTIC OCEAN... High pressure ridging extends across the western Atlantic to south Florida, allowing for moderate to fresh southerly flow offshore Florida and the Bahamas, noted in a recent scatterometer pass. Areas of locally strong winds are noted within 90 nm of the Lesser Antilles. Seas in this area are generally 4 to 6 ft. Farther east, high pressure ridging extending from the Azores high dominates the waters north of 23N.

Another area of fresh to strong winds is noted south of 20N between 30W and the Lesser Antilles, where seas are 6 to 8 ft. Elsewhere, flow is gentle to moderate with 4 to 6 ft seas. For the forecast west of 55W, fresh winds offshore Florida should generally continue into Thu night, before a cold front moves offshore the SE U.S. This front will reach from 31N72W throug the central Bahamas and central Cuba Fri night. Strong NW winds will develop offshore N Florida behind the front this weekend. $$ Mora
