Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...Winds will pulse to gale force each night and early morning offshore of Colombia through early next week. Moderate to fresh trade winds and moderate to locally rough seas will occur across the central and eastern Caribbean through Mon night as the pressure gradient tightens between high pressure in the western Atlantic, and the Colombian low. Locally strong winds will pulse across the Windward Passage, downwind of Hispaniola and in the lee of Cuba through early next week. Otherwise, long- period E swell will combine with a new N swell this weekend to produce locally rough seas in the tropical Atlantic waters east of the Windward and Leeward Islands and their passages into the Caribbean.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Moderate to fresh winds and rough seas to 10 ft will continue to affect the offshore waters N of 28N and E of 70W through Sat, extending also across the offshore waters E of the Bahamas tonight into Sat as high pressure builds N of the area. This will lead to locally strong trade winds and rough seas in E swell south of 25N through early next week. A cold front is expected to progress offshore of the southeastern coast of the United States on Fri, producing fresh to strong winds and rough seas in its wake. Looking ahead to Mon, high pressure along 30N will support gentle breezes north of 25N, and moderate to fresh E winds and moderate to rough seas in E swell south of 25N, except for locally strong winds in the approaches of the Windward Passage.
