Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1024 AM EDT Wed Jun 19 2024

.SYNOPSIS...Strong surface high pressure centered off the New
England coast working in tandem with falling pressures over the
Yucatan Peninsula and the Bay of Campeche will result in moderate
to fresh breezes this afternoon through late week. A weak area of
low pressure will begin to develop later this afternoon a few
hundred miles north of the central Bahamas and move towards the
Southeast U.S. coastline. This will lead to slackening east to
southeast breezes for Friday through the weekend.
