Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas

.SYNOPSIS...
A Small Craft Advisory is in effect for all Florida Keys marine
zones. High pressure over the eastern United States, and a weak
low northeast of the Bahamas will sustain fresh to strong breezes
through the weekend and early next week. Peak breezes are expected
on Sunday night through Tuesday in which near gale wind gusts
will be possible over the Outer Gulf waters. Freshening breezes
and pulses of low level moisture may support elevated shower
chances on Sunday night and Monday. Breezes are on track to
slacken to moderate to fresh by midweek.
