Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1019 PM EDT Sat Jun 27 2026
.SYNOPSIS...A broad high pressure system centered over the North
Atlantic will continue to extend westward to the Florida Peninsula
through early next week. This will support bouts of light to
gentle breezes that may freshen to gentle to moderate at times,
mainly in the overnight hours. Starting late Monday, a frontal
boundary will press south across the Florida Peninsula and stall
across central Florida. This will act to weaken the high and
allow for slackening breezes through Wednesday. Thereafter, a
broad area of low pressure may develop along the residual stalled
frontal boundary and move westward across Florida. This could
potentially freshen breezes once again.
