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

.SYNOPSIS...A broad area of surface high pressure sliding
eastward in the central North Atlantic will lead to gentle to
moderate east to southeast breezes. As the axis of the associated
ridge sags slightly further southward across the Florida
Peninsula late this week, moderate to occasionally fresh breezes
will be possible. A surge in moisture through Thursday will
support elevated rain and thunder chances, with drier conditions
expected for Friday through the weekend.
