Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1023 AM EDT Tue Sep 17 2024

.SYNOPSIS...Light and generally variable breezes will continue
through Saturday across the Florida Keys coastal waters. Winds
and seas will be elevated in and around thunderstorms,
particularly on Tuesday and Wednesday, though background winds
will remain light and variable. Northerly swell generated by the
low pressure on the Eastern Seaboard will linger through Tuesday
and Wednesday. This disturbance will deepen into an upper level
trough and slowly slide south towards the Florida Peninsula
through Saturday. Unpredictability in the movement of this trough
means confidence in the extended forecast is very low.

of September 10...
