Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1033 AM EDT Mon Jul 27 2026
.SYNOPSIS...Troughing just off the Eastern Seaboard will remain
for the next day or so before another trough swinging
southeastward through the Great Lakes and into the Northeast
reinforces the trough across the East Coast. At the surface, this
will result in a frontal boundary remaining draped across
northern Florida/Georgia for much of this week. Initially, expect
west to northwest light to gentle breezes before shifting to the
southwest to west by Tuesday. Breezes will become gentle to
moderate towards mid week before slackening back to light to
gentle by late week.
