Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N59W to 27N66W to
30N77W will merge with a reinforcing cold front today and then
weaken into a frontal trough on Fri. Strong high pressure N of
the area and in the wake of the front will lead to strong to
near gale force easterly winds across the N waters, mainly N of 
27N, today through Sat night. Large NE swell following the front 
will push southward across the entire area over the weekend. 
Looking ahead, a complex, non-tropical area of low pressure is 
expected to develop Sat night over the NE Caribbean Sea or the SW
N Atlantic. Some slow subtropical or tropical development of 
this system is possible afterward while it moves generally N to 
NW through early next week.
