Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1031 AM EST Sat Dec 21 2024
.SYNOPSIS...A broad high pressure system will slide across the
eastern United States today through Sunday, resulting in breezes
gradually clocking around to the northeast. Early next week a
coastal trough will develop from the Carolinas south to the
Florida Peninsula. This will result in a brief period of
freshening northeast to east breezes. A second, strong high
pressure system will settle into the Eastern Seaboard towards
midweek resulting in another period of freshening breezes with the
potential for fresh to occasionally strong breezes.
