GMZ005-170245- Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas 435 PM EDT Sun Jun 16 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 near mid week and move towards the north to central Florida coastline. This will result in slackening breezes before high pressure takes control again resulting in freshening east to southeasterly breezes late week.
