...Gulf of Mexico...

Latest satellite derived winds and seas along with surface observations indicate moderate to fresh NE to E winds across the basin. Seas are 4 to 6 ft across the central and southern Gulf and 2 to 4 ft across the northern Gulf. A trough will develop over the Yucatan Peninsula each evening and shift westward across the southwest Gulf during the overnight hours. Winds will pulse to fresh to strong WNW of the peninsula mainly during the late afternoon and evening hours. Otherwise, high pressure will prevail over the forecast waters through Mon. Se winds will increase to fresh to strong in the NW Gulf Fri night into early Sat, then will diminish. The pressure gradient will tigthen early next week with fresh to strong return flow possible across the majority of the basin late Mon night through Tue night.

...Caribbean Sea and tropical N Atlantic from 07n to 19n between 55w and 64w...

High pressure ridging over the western Atlc will support fresh to locally strong trades across the south central Caribbean the next several days. Winds will reach near gale force along the NW coast of Colombia during the overnight hours. Seas will occasionally build to 10 to 12 ft near the strongest winds. NE winds across the approach to the Windward Passage and in the Lee of eastern Cuba will increase to fresh to strong Fri night, and will continue to pulse to fresh to strong through early next week. Otherwise, moderate to fresh trades will prevail across the basin for the next several days.

Undersea Volcano kick EM jenny, north of Grenada near 12.18n 61.38w, is in a state of unrest. The government of Grenada advises mariners to observe a 5 km or 3.1 nm exclusion zone around kick EM jenny. Please see www.Nadma.Gd for additional information.

...SW N Atlantic including the Bahamas...

A cold front extends from 31n65w to eastern Cuba, ahead of a reinforcing front reaching from 31n70w to central Cuba. Mainly moderate to fresh winds follow and precede the fronts. Seas are up to 8 to 12 ft N of 25n behind the front to 77w. The fronts will merge before stalling across the far se waters this weekend. A reinforcing cold front will drop S of 31n Fri night with fresh to strong winds following it across zones amz113-115 through Sat night, diminishing as the front exits, with high pressure building in its wake. Another cold front may drop S of 31n sun through early next week with fresh to locally strong winds and large northerly swells spreading across the basin in its wake.
