Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
420 AM EDT Wed Jun 5 2024

.SYNOPSIS...An Atlantic pressure ridge will extend westward
along the Gulf Coast today. As a result, gentle to moderate
easterly breezes will persist, peaking during the afternoon and
evening hours. Thereafter, the ridge will shift southward across
Florida, resulting in slackening and, at times, variable breezes.
Winds may perk up out of the south late this weekend as the Gulf
of Mexico portion of the ridge weakens and pressures fall in the
northwestern Caribbean Sea.

The Approximate Shoreward Edge of the Gulf Stream as of June 4,
2024...
