Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Strong NE winds and rough seas occurring along and to the west of a trough, extending southwestward from a 1011 mb low near 25N71W through eastern Cuba, will persist through Sunday. There is a low chance of tropical formation along this trough within the next 48 hours and next 7 days. A strong cold front will continue to progress southward through the central and western Atlantic this weekend, reaching 23N by Sun morning and 19N by Mon before stalling through Tue. Expect widespread fresh to strong NE to E winds and rough to very rough seas in N swell north of the front through early Mon before diminishing through Tue. N swell will reach the NE Caribbean Mon morning and the Tropical Atlantic waters Mon afternoon and night. Elsewhere, moderate to locally fresh E trades and moderate to rough seas will occur east of the Windward Islands through the forecast period. Another cold front moving off the southeastern U.S. coast will lead to another round of fresh to strong NE winds and rough seas north of the Greater Antilles and west of 55W by the middle of next week.
