Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1035 AM EDT Mon Jun 30 2025
.SYNOPSIS...Broad low-level ridging will continue to rebuild over
the North Atlantic and support gentle to moderate east to
southeasterly breezes across Florida Keys coastal waters, veering
to the southeast to south and modestly slackening throughout the
week. An upper- level low east of the Bahamas will slide slowly
northwestward towards the Florida east coast early this week,
supporting slightly enhanced rain and thunder chances. Rain
chances briefly taper back mid-week before increasing again late
this week due to a new weather disturbance sliding into the
Southeast US.
