Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
427 PM EDT Mon May 11 2026
.SYNOPSIS...Southeasterly breezes have slackened due to a weak
frontal boundary moving into the northern Gulf. Dry layers of air
above the surface will keep shower chances low through tonight,
though the front may be able to bring a plume of moisture and
increased rain chances as early as Tuesday. Periods of variable
winds are expected during the week, and there is high confidence
that breezes will remain light throughout the week.
