Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
423 AM EST Sat Nov 15 2025
.SYNOPSIS...High pressure centered over the Southeast U.S. will
continue to move southward over the weekend. This will promote
gentle to moderate breezes this morning. Breezes will continue to
slacken later today as the high weakens and flattens. Due to the
weak flow, there may be a period of light and variable breezes
Sunday through Monday. Another high will traverse across the
eastern United States early next week while slowly strengthening.
This will allow for freshening northeast to east breezes through
mid week.
