Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1025 AM EST Sun Nov 8 2026
.SYNOPSIS...
A robust high pressure system over the southeastern United States
will spread eastward over the next few days. As a result, light
to gentle northeasterly breezes will gradually shift further
northeasterly and freshen early this week. As the high slides
further southeastward into the west-central North Atlantic,
breezes will clock around to the east and modestly slacken by mid
week. A strong cold front is expected push through the Keys
marine zones late Thursday night, with breezes backing to the
northwest and freshening in its wake.
