Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
417 PM EST Mon Nov 24 2025
.SYNOPSIS...A continental high will gradually push offshore over
the next couple of days, resulting in freshening northeast to
east breezes. As the center of this high progresses eastward into
the western North Atlantic, breezes will collapse by midweek, as
the pressure field becomes nebulous. Probability is increasing
that a cold front will push southward through the Florida Keys
coastal waters later this week before stalling, resulting in what
appears to be the start of a prolonged period of freshened
northeast to easterly breezes through the weekend.
