 Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
 428 AM EDT Fri Apr 3 2026
 
 
 .SYNOPSIS...Expansive and strong high pressure across the central
 North Atlantic will continue to dominate the pattern through at
 least the first half of the weekend. This will continue to promote
 moderate to fresh easterly breezes, occasionally strong in the
 Florida Straits. Breezes will tend to peak overnight into the
 morning hours, and lull in the afternoon. This high will begin to
 retreat to the east as we head into the start of next week,
 allowing for breezes to slacken.
