Gale Warning

Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1016 AM EDT Mon Oct 26 2026
.SYNOPSIS...
Sprawling high pressure over the eastern United States will be
reinforced by a secondary high north of the Dakotas. As these
features interact with a persistent low south of the Bahamas, this
will sustain frequent near gale gusts this afternoon through
Tuesday morning, especially across the Straits of Florida, extreme
eastern Hawk Channel, and the SE Gulf waters. In addition, pulses
of low level moisture will support elevated shower chances,
mainly in the eastern marine zones. The secondary high will slide
into the central North Atlantic for the middle to latter part of
the work week, supporting slackening breezes. However, wave
heights will stay elevated through mid week.
