GMZ005-051430- 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.
