Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A broad inverted trough accompanied by active
weather extends from near 31N66W to 20N75W to eastern Cuba will 
continue to shift W to the central Bahamas through Sun night while
weakening. Atlantic high pres is drapped across the waters N of 
the trough, and is producing fresh winds and seas to 9 ft E of 
the trough. Winds and seas across the region will gradually 
diminish through late Sun as the high pres weakens. A strong cold 
front has moved offshore the SE U.S. and will sink across the 
waters of NE Florida 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 and
gradually weaken along 24N/25N by the middle of next week.
