GMZ005-010900- Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas 1021 PM EDT Sun Jun 30 2024 .SYNOPSIS...Tropical Depression 3 located in the southwestern part of the Bay of Campeche will move inland overnight and dissipates. The western periphery of the subtropical high over the Atlantic will maintain modest control over the Keys. This will result in mainly gentle to moderate breezes over the next few days, occasionally light to gentle. Tuesday through late week, breezes will freshen as the gradient between the subtropical high over the Atlantic and Beryl (major hurricane) strengthens. Beryl is expected to remain well south of the Florida Keys as it marches west northwest through the Caribbean Sea. Please review the Tropical Cyclone Advisories for additional information on the track and future evolution of Beryl.
