Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
452 AM EST Fri Feb 6 2026
SYNOPSIS
Moderate to fresh breezes, though fresh to strong for
the Straits of Florida, will continue early this morning in the
wake of a strong cold frontal passage. As the front continues to
push away from the Florida Keys today, 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.
