Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
445 PM EDT Wed Aug 5 2026
.SYNOPSIS...Gentle easterlies will become moderate by this
evening, continuing through early next week, as nearby Atlantic
ridging strengthens and lifts northward towards North Florida. In
addition, rain chances will remain elevated through the end of the
work week, as pockets of deep moisture and slightly cyclonic
upper- level curvature push through the region at times. Higher
winds and seas should be expected in the vicinity of thunderstorm
activity. As the upper-level support wanes over the weekend, rain
and thunder chances will decrease.
