Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 PM EDT Wed Jun 11 2025

.SYNOPSIS...A broad area of surface high pressure in the central

slightly further southward and the high nudges westward, moderate
to occasionally fresh breezes will be possible Thursday through
at least Saturday night. A surge in moisture through Thursday will
support elevated rain and thunder chances, with drier conditions
expected for Friday through the weekend.
