Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
424 PM EDT Tue May 5 2026
.SYNOPSIS...A poorly defined wind field with light and variable
breezes will persist until ridging can become better established
across the Florida peninsula on Wednesday. At that point, winds
will become a climatologically appropriate light to gentle east to
southeasterly breeze. Deep layered ridging will dominate from mid
week through the remainder of the work week. This along with very
weak forcing will keep rain chances out until at least Saturday
when southeasterly breezes strengthen to gentle to moderate,
bringing in increased boundary layer moisture and opening the door
to maritime showers.
