Marine conditions are expected to deteriorate across the region on Thu afternoon as the low pressure deepens over the SE of United States. Strong to minimal gale force winds are expected across the northern waters Thu night and Fri. As a result, the forecast calls for gale conditions possible across much of the forecast waters N of 22N Thu night and Fri. Seas are expected to build in the 16-20 ft range across the eastern half of the Gulf by Fri. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...

The front will dissipate by tonight, and its remnants will then move westward as a trough across the NW Caribbean on Tue. The trough will then reach the Yucatan Peninsula by Tue night. Fresh to strong winds will persist across the south-central Caribbean through the forecast period, with the strongest winds near the coast of Colombia, reaching near gale force mainly at night. The next cold front is forecast to enter the NW Caribbean by late Thu followed by fresh to locally strong NW winds, and building seas of up to 8 or 9 ft. ...SW N ATLANTIC INCLUDING THE BAHAMAS...
