Synopsis for the SW N Atlantic including the Bahamas
330 PM EST Mon Dec 8 2025
.SYNOPSIS...A cold front extending from southwest of Bermuda to
just northeast of the Bahamas will progress eastward early this
week, and fresh to strong SW winds are expected ahead of the front
north of 27N through Tue. Rough seas in W swell will develop in
this region east of 73W today, and expand eastward into the
central Atlantic by tonight. Very rough seas over 12 ft will be
possible north of 30N and east of 64W by Tue morning. A second,
stronger cold front extending from 31N75W to central Florida will
rapidly progress eastward through midweek, and widespread fresh to
strong N to NW winds are expected in the wake of the front,
generally north of 27N and west of 65W by late tonight, with these
winds also expanding eastward toward the central Atlantic through
Tue. A new N swell will support rough seas over the northwest
tropical Atlantic by late tonight, before merging with the
aforementioned rough seas in the central basin on Tue. Winds will
diminish from west to east through Tue night, with rough seas
slowly subsiding through late week. Looking ahead, fresh to
locally strong SW winds and rough seas may develop off the coast
of Florida mid to late week as a low pressure system moves off the
east coast of the U.S.
