Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas 1024 AM EDT Mon Apr 15 2024

SYNOPSIS
Gentle to moderate northeast to east breezes will continue this afternoon across the Florida Keys coastal waters. High pressure east of the Florida Peninsula will continue to slide into the west- central North Atlantic, then remain in place through the middle of the week. This will result in easterly moderate to modestly fresh breezes. A secondary high pressure moving in from the Central Plains will gradually blanket the Gulf of Mexico, with slackened east to southeast breezes expected for the end of the week.

The Approximate Shoreward Edge of the Gulf Stream is currently unavailable.
