Southeast Gulf of America

SYNOPSIS
A high pressure ridge extends from the western Atlantic to the central Gulf. The combination of the ridge and broad low pressure over Texas and northern Mexico associated with a trough has lead to a tightening of the pressure gradient over the western and central waters bringing moderate to fresh southerly return flow across those waters. It is expected to continue into early Fri evening. Looking ahead, low pressure that is currently over the High Plains region will send a cold front to the NW Gulf on Sat afternoon, followed by fresh to near gale north to northeast winds expected Sat night through Sun night. Gale conditions are possible offshore Tampico on Sun and offshore Veracruz Sun afternoon and Sun night. Mariners are urged to stay up to date with the latest forecasts.

SYNOPSIS
A cold front extends from 29N55W to 26N63W, where it becomes a stationary front to the central Bahamas. The cold front will reach from near 27N55W to 26N60W, and weakening stationary front to the central Bahamas this morning. The cold front will become a weakening stationary front from 25N55W to near 23N67W by early Wed evening, then weaken and dissipate Thu. Fresh to strong southwest winds ahead of the cold front north of 29N will shift north of 31N this morning. Behind the front, large to very large N swell will occur with 12 ft or greater seas sliding east of 55W north of 28N tonight. Seas of 8 to 10 ft will propagate southward reaching to near 20N on Thu, then shifting east of 55W on Fri while subsiding. Light to gentle anticyclonic winds are expected for most of the offshore zones from this evening through Sat night as a high pressure ridge initially builds westward near 27N before it shifts southeastward Sat through Sun night in response to a frontal system that will be moving through the southeastern U.S. A strong cold front with this system is expected to push off the Georgia and NE Florida coasts on Sun, followed by increasing NW winds and building seas.
