Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 AM EDT Thu Jul 4 2024

.SYNOPSIS...Hurricane Beryl will continue its trek across the
Caribbean Sea well to our south, but the increased pressure
gradient will allow for a short period of moderate breezes through
this afternoon and evening. These breezes will slacken tomorrow as
Beryl moves farther away, and high pressure will lead to gentle
east to southeasterly breezes veering to the southeast and south
through the end of the week and into the weekend.

50 NM South of Dry Tortugas Light...on Loggerhead Key.
