Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
424 AM EST Sun Nov 16 2025
.SYNOPSIS...Weak high pressure will continue to promote light to
gentle breezes today through Monday. Due to the weak flow, there
may be periods of light and variable breezes, mainly in the
afternoons. Another high pressure system will traverse across the
eastern United States early this week while slowly strengthening.
This will allow for freshening northeast to east breezes for the
middle and latter part of the week.
