Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...High pressure east of the Bahamas will drift S and 
weaken through Tue. A weak cold front will move into the far 
northern waters late tonight and stall early Tue, then lift N as
a warm front later Tue as strengthening low pressure moves off
the SE U.S. coast. This low will pull a strong cold front across
the waters Tue night through late this week. Expect SW gales and
building seas across the northern waters ahead of the front Tue 
night and Wed. Gales are also possible S of Bermuda Wed night 
behind the front. Elsewhere, northerly swell will propagate 
southward across the region Wed through Fri night.
