Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1029 PM EDT Fri Jun 5 2026
.SYNOPSIS...An expansive eastern United States surface high will
move off the Carolina Coast will push into the Atlantic over the
next few days. As a result, mostly moderate easterly breezes will
gradually give way to gentle to moderate easterlies this weekend.
The recent bout of increased shower and thunderstorm activity is
nearing its end, and convective potential will fall closer to
normal through this period. Early next week the high will have
pushed out into the Atlantic and weak troughing is expected to set
up over Cuba and the Bahamas. This will tip breezes a bit further
southeasterly with, initially, some additional slackening. By
midweek, unsettled weather and increased rain and thunder chances
will return to the Keys.
