Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...A weakening stationary front lies over Haiti and near the Windward Passage. This feature will weaken further and dissipate later this evening. Moderate to locally fresh NE winds near the Windward Passage will persist through early Sat morning. Farther south, moderate NE to E winds offshore of northwestern Colombia and in the Gulf of Venezuela will peak at fresh to strong during the evening and early morning hours through Mon night, rough seas are also expected during these peak winds. A similar scenario is also anticipated in the Gulf of Honduras tonight through Sat night. Looking ahead, a cold front moving through the Gulf of America this weekend is slated to enter the northwestern Caribbean by early next week, leading to fresh to locally strong N winds and locally rough seas in its wake.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 31N56W to the north coast of Hispaniola will continue to progress eastward through the weekend. Fresh to locally strong SW to NW winds will linger ahead and behind this front through early this evening. As this front lifts northeastward tonight, winds will steadily diminish. A large area of very rough to high seas generated by large northerly swell will shift eastward across the western and central Atlantic through this Sat night, before gradually decaying Sun and Mon. High pressure currently over the northwest Bahamas will shift eastward into the western Atlantic, as a complex low pressure system strengthens north of the area. The pressure gradient between these features will support moderate to fresh SW winds north of 29N and west of 70W by late tonight, and west of 60W on Sat. Looking ahead, a cold front is anticipated to exit the coast of the southeastern United States early next week, causing fresh to locally near-gale winds and very rough seas east of Florida, and northeast of the Bahamas. Some of these winds might reach gale force Mon night through Tue. ATLC waters from 27N to 31N W of 77W ...GALE CONDITIONS POSSIBLE MONDAY NIGHT AND TUESDAY... .TONIGHT...SW winds 10 to 20 kt.
