Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
429 AM EST Tue Dec 2 2025
.SYNOPSIS...High pressure across the area will continue to
promote gentle to moderate southeast breezes this morning as it
shifts into the western North Atlantic. A developing storm system
on the heels of this high will result in a weakening of the
pressure gradient across the Keys through early Wednesday. Its
corresponding cold front is expected to press through the Keys mid
to late week resulting in freshening north to northeast breezes.
Another surface high builds back in following the front with
gentle broadly southern breezes returning in time for the weekend.
