Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
418 PM EDT Mon Jun 17 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 is expected to result in
moderate to fresh breezes tonight through mid week. An area of
low pressure may develop mid week a few hundred miles north of the
central Bahamas towards mid week and move towards the north to
central Florida coastline. This may result in a brief slackening
of breezes before high pressure takes control again resulting in
freshening east to southeasterly breezes late week.
