Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
432 AM EST Thu Nov 5 2026
.SYNOPSIS...
A weak ridge will stretch southwestward across the Florida
Peninsula today, keeping gentle northeast to easterly breezes
today. Breezes will slacken heading into the weekend as the ridge
weakens and shifts southward into South Florida and the Keys.
There is a potential for brief nocturnal surges each night through
the next several days. In addition, drier air filtering through
the lower levels will keep near normal rain chances. A surface
high will develop across the Gulf beginning Friday, which may lead
to brief nocturnal wind surges along the west coast of Florida
and into the outer Gulf waters.
