A surface ridge will dominate the Gulf waters through the weekend, supporting mainly gentle to moderate winds and slight to moderate seas. Winds off the western Yucatan Peninsula and in the Bay of Campeche will pulse to fresh tonight. CARIBBEAN SEA...

Strong E winds, and sea heights that reach 7 feet, have been in the coastal waters of Colombia. Gentle to moderate NE to E winds, and sea heights that range from 2 feet to 4 feet, are elsewhere. Fresh to locally strong E winds will prevail in the south central Caribbean Sea into the weekend. Elsewhere, mainly moderate trade winds will dominate. ATLANTIC OCEAN...

Precipitation: isolated moderate to locally strong covers the area of the upper level cyclonic wind flow. Gentle to moderate NE winds, and sea heights ranging from 3 feet to 5 feet, are within 120 nm to the northwest of the trough. An upper level trough extends from a 33N46W cyclonic circulation center to 19N49W. Precipitation: isolated moderate to locally strong is within 150 nm on either side of the upper level trough. Broad surface anticyclonic wind flow covers the Atlantic Ocean from 16N northward from 60W eastward. A 1034 mb high pressure center is near 42N40W. Light to gentle breezes, and sea heights that range from 2 feet to 4 feet, are elsewhere from 60W westward. The subtropical ridge covers the waters that are from 20N northward. Mostly moderate NE to E winds are in the Atlantic Ocean. The sea heights range from 5 feet to 7 feet from 20N northward, and they range from 3 feet to 5 feet from 20N southward. A trough in the eastern waters will dissipate into Fri. Fresh to strong SW winds will develop over the NW waters tonight and continue through Thu night as low pressure moves offshore the SE U.S. north of the area. $$ mt/al
