Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1030 PM EST Fri Dec 26 2025
.SYNOPSIS...High pressure centered over the northeastern Gulf
will support light to gentle mainly north to northeast breezes.
The high will weaken as it drifts slowly southeastward through the
weekend, leading to slackening breezes. A potent cold front is
expected to move through the Keys towards the middle part of next
week. This will lead to freshening northerly breezes throughout
all the Florida Keys coastal waters.
