Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
435 AM EDT Wed Jun 3 2026
.SYNOPSIS...
The combination of a robust eastern United States surface high and
and a deepening Gulf low will result in light breezes this
morning freshening to at least gentle to moderate. Uncertainty is
high, and periods of higher breezes will be possible. Additional
perturbations are likely due to an expected increase in
convective activity in association with an approaching weak
frontal boundary. Shower and thunderstorm chances will remain
quite elevated through much of the remainder of the week. The
threat of periods of higher breezes will remain. Rain chances
should trend downwards towards normal through the weekend as drier
air moves in and winds diminish.
