Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front currently south of 30N and W of 70W
will merge with a frontal trough that extends from 31N61W to the
eastern Dominican Republic tonight. The front will reach from 
near 31N58W to eastern Cuba by Sat morning, and from near 25N55W 
to Hispaniola by Sun morning, then stall and weaken over the far 
southeastern part late Sun through Mon night. North swell behind 
the front will build seas to a peak of 12 ft over northeast 
offshore waters by Sun. Strengthening high pressure in the wake 
of the front will result in fresh to strong north to northeast 
winds behind the front from tonight through Sun. By late Sun, 
fresh winds will prevail in the wake of the weakening front and 
continue through Mon. Tranquil conditions are expected Tue as 
high pressure becomes centered over the NW part of the offshore 
waters, with the induced gradient supporting fresh northeast to 
east winds over the southern waters.
