Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
605 AM EDT Sun Oct 6 2024

.SYNOPSIS...Light mainly southeast breezes will continue through
the rest of the weekend, coupled with bouts of rainy and thundery

Gulf Coast early next week. Regardless of the eventual strength
and track of the system, an extended period of above normal rain
and thunder chances along with freshening breezes and building
seas are expected for the Florida Keys coastal waters next week.
Small Craft Advisories are likely and Gale or Tropical warnings
cannot be ruled out.
