Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A tight pressure gradient between lower pressure in the Caribbean and high pressure over the central Atlantic will lead to moderate to fresh winds south of 27N through Thu night. A cold front will move off the southeastern U.S. coast Thu night, with some strong southwest winds ahead of it, north of about 29N. These winds will spread east as the front reaches a line from Bermuda to the southeastern Bahamas to central Cuba this weekend and stalls. Some strong north winds are possible behind the front north of about 29N this weekend. A stronger cold front will sweep across the western half of the area early next week followed by strong to near gale force north to northeast winds and building seas, mainly north and northeast of the Bahamas. The northern part of a tropical wave will move across the far SE waters this through Thu night followed by fresh to strong east winds along with scattered showers and thunderstorms to impact most of the eastern Greater Antilles and also the southeastern Bahamas.
