Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1030 PM EDT Tue May 6 2025

.SYNOPSIS...
An Atlantic ridge will continue to nudge further west as it lifts
north into the Florida Peninsula over the next couple of days.
Meanwhile, surface troughing will develop over the western Gulf.
As a result, light southeasterly breezes will freshen tonight.
Small Craft Should Exercise Caution for increasing winds in the
Straits of Florida tonight. After mid week, the pressure pattern
will be sloppy with ridging being the main driver for seasonable
east to southeasterly breezes.
