Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 PM EDT Tue Oct 14 2025
.SYNOPSIS...A low pressure system continues to push off and away
from the Eastern Seaboard, while a high pressure system builds
over the eastern United States. This will result in moderate to
fresh breezes overnight. Slackening winds are expected on
Wednesday as the low moves further east across the North Atlantic.
By the end of the week, high pressure will set up along the
Carolina coast and support freshening breezes. Expect peak breezes
during the late evening to mornings, and lulls in the afternoons.
Shower coverage will remain isolated to scattered.
