Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A broad inverted trough accompanied by very active
from near 31N65W to 20N71W will shift W and weaken through Sun, 
while reaching the central Bahamas. Atlantic high pres is drapped
across the waters N of the trough, and is producing fresh winds 
and seas to 10 ft E of the trough. Winds and seas across the 
region will gradually diminish through Sun as the high pres 
weakens. A strong cold front is expected to move offshore of the 
SE U.S. and NE Florida today through early Sun, and sink SE 
across NW portions, reaching from near Bermuda to central Florida 
Sun evening, and from 31N60W to SE Florida by Mon evening. A large
area of strong to gale-force N to NE winds, storm-force 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 may stall along 25N/26N by the middle of next week.
