Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1021 PM EST Thu Feb 5 2026
.SYNOPSIS...Fresh to strong breezes will continue through Friday
morning in the wake of a strong cold frontal passage. As the front
continues to push away from the Florida Keys on Friday, breezes
will somewhat slacken, although marine conditions will remain
hazardous. An area of high pressure will build across the Mid-
Atlantic over the weekend, supporting moderate northwest breezes.
As the high slides southeastward late Sunday through early next
week, breezes will slacken and clock around to the northeast.
