 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.
