Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1028 PM EDT Thu May 7 2026
.SYNOPSIS...A series of weak high pressure systems in the west-
central North Atlantic will support light to gentle, mainly
southeasterly, breezes over the next several days. Strong
upper-level ridging across the Gulf eastward to the Bahamas will
also yield near- nil rain and thunder chances through the
weekend. As a weak frontal boundary approaches the Florida Keys
early next week, there may be a slight uptick in rain and thunder
chances.
