Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1021 AM EST Thu Feb 26 2026
.SYNOPSIS...
A broad Atlantic ridge will shift eastward over the next few
days. Through this period, resulting gentle to moderate east to
southeasterly breezes will slacken. However, impacts from nearby
land breezes and cooler waters north of the island chain will make
conditions more chaotic. Over the weekend, a high pressure system
is primed to build over the southeastern States. Breezes will
slacken to light to gentle amidst an increase in shower coverage.
A reinforcing high is forecast to sweep into the eastern US in the
latter half of the weekend, and may prompt rapidly freshening
breezes early next week.
