Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A broad inverted trough accompanied by active weather extends from near 29N69W to 26N72W then central Hispaniola, and will continue to shift W to the central Bahamas through Sun night while weakening.

Winds and seas across the region will gradually diminish through late Sun as the high pres weakens. A strong cold front is expected to move offshore of the SE U.S. this evening and sink across the waters of NE Florida tonight through early Sun. The front will then move SE across NW portions, reaching from near Bermuda to central Florida Sun night, and from 31N62W to S Florida by Mon evening. A large area of strong to gale-force N to NE winds, with storm-force winds just N of 31N, and significant NE swell, will build into the area behind the front, spreading across the waters N of 26N and W of 65W by Tue. The front is expected to stall along 24N/25N by the middle of next week. ATLC waters from 27N to 31N W of 77W ...GALE WARNING... .TONIGHT...S winds less than 10 kt.
