Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
420 AM EDT Wed Jun 10 2026
.SYNOPSIS...A high pressure system over the North Atlantic will
provide support for persistent gentle to easterly breezes across
the waters surrounding the Florida Keys. Shower coverage is
expected to peak this afternoon while an easterly wave moves
across western Cuba. The high pressure system is primed to move
further east into the Atlantic, which will allow breezes to
slacken to light to gentle. At the same time, the easterly wave
will pull the flow of moisture west and allow a drier pattern to
set up across the Keys. Shower and thunderstorm chances this
weekend are expected to be low as a result.
