Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Strong to near gale-force winds and rough seas are occurring to the north and west of a 1011 mb low, centered near 24.5N72.5W. These winds will diminish to strong speeds today as the low moves W and weakens. A strong cold front will continue to progress southward through the central and western Atlantic through Mon, reaching along 23N this evening, and along 19N-20N by Mon before stalling and weakening through Tue. Expect widespread fresh to strong NE to E winds and rough to very rough seas in N swell to follow the front through Mon morning before diminishing 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 Tue evening 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 this week.
