Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front associated to a large area of complex low pressure north of the area extends southwestward to 28N55W and to 27N70W. Gale-force winds will develop this afternoon north of 29N between 62W and 65W. These conditions will diminish to just below gale-force tonight and into Sun as the complex area of low pressure shifts eastward and weakens. The cold front will also weaken as it shifts east of the area by late Sun night. Large long-period north to northeast swell will continue to impact the Atlantic waters and Caribbean Passages between the southeastern Bahamas and the eastern Caribbean, producing high seas into the start of next week. Long-period east swell is expected to reach the Florida offshore waters north of 27N well into next week. ATLC waters from 27N to 31N W of 77W .TODAY...NE winds 10 to 15 kt.
