Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1043 AM EDT Thu Apr 23 2026
.SYNOPSIS...High pressure over the western North Atlantic will
slowly crawl away from the area, and breezes will gradually
slacken over the course of the next day or two. As the high
continues to slowly migrate farther into the western North
Atlantic, breezes will continue to slowly slacken as well as shift
to the east to southeast. Weak high pressure maintains control
over the weekend into early next week promoting light to gentle
east to southeast breezes.
