Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 AM EDT Mon Sep 16 2024

.SYNOPSIS...Light and generally variable breezes will continue
through Friday over the Florida Keys coastal waters. A developing
low pressure system off the Carolina coast will generate a higher
northerly swell off the Upper Keys for Tuesday and Wednesday. The
low will deepen into an upper level trough and slowly slide south
towards the Florida Peninsula by Friday. Unpredictability in the
movement of this trough means confidence in the extended forecast
is very low.
