Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 AM EDT Wed May 28 2025

.SYNOPSIS...Gentle to moderate east to southeast breezes,
occasionally southeasterly, will continue through the end of the
week as a ridge remains over the western North Atlantic. Breezes
will peak late evening into the morning hours and lull in the
afternoon. Confidence continues to grow on a wetter regime
heading through the weekend and into early next week as moisture
increases. A low pressure system will develop along the DELMARVA
region with a trailing cold front to northern Florida. This front
will struggle to push south along the Florida Peninsula but it
will result in southeasterly winds shifting to the southwest to
west over the weekend.
