Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N78W to northeast
Florida will reach from near 31N70W to the Straits of Florida
Tue morning, from near Bermuda to the central Bahamas by Tue 
afternoon, then weaken as it reaches from near 31N56W to eastern 
Cuba by Wed morning. Fresh to strong winds and rough seas are 
expected ahead and behind the front. Winds are forecast to reach 
minimal gale force tonight into Tue, affecting mainly the waters
