Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
450 AM EST Mon Dec 22 2025

.SYNOPSIS...Strong high pressure centered the Virginias this
morning will move off the North Carolina Coast tonight. The high
then moves farther out into the North Atlantic slowly weakening
and flattening as a low pressure system develops off the New
England Coast. This will promote fresh to strong northeast to east
breezes this morning, peaking this afternoon and tonight. Another
high moves in behind the low pressure system off the New England
Coast Tuesday and Tuesday night. This will result in fresh
northeast to east breezes persisting through Christmas Eve and
Christmas Day. Breezes will diminish Thursday night through Friday
night as the high weakens and flattens.
