Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Fresh to strong S winds and rough seas will occur off the coast of Florida late tonight through Sun as low pressure strengthens over the southeastern United States. Strong winds will expand farther east on Sun, impacting areas north of 28.5N and west of 60W through Sun night. A cold front associated with the low will move into the waters Sun night, leading to fresh to locally strong NW to W winds behind the front north of 28N and west of 70W. Winds will diminish on Mon as the front moves eastward and eventually dissipates. Elsewhere, a cold front that extends from 31N39W to 28N58W, becoming a stationary front and extending to 28N71W, will dissipate on Sun. Rough seas associated with this front will expand farther south and east overnight, and produce rough seas across areas north of 23N and east of 68W by Sun morning. Locally very rough seas of 12 to 14 ft will be possible north of 28N and east of 60W through Sun morning. Farther south, fresh trade winds and rough seas will prevail south of 23N through the middle of next week, with locally strong winds pulsing north of Hispaniola and through the Windward Passage.
