Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1029 PM EDT Sat Jun 1 2024

.SYNOPSIS...High pressure just off the eastern North Carolina
coastline will continue moving farther southeast into the western
North Atlantic overnight, resulting in moderate to fresh easterly
breezes across the Keys coastal waters. The high will set up over
the western North Atlantic from Sunday through the middle of next
week while slowly weakening. This will result in gentle to
moderate breezes peaking in the afternoon and evenings and lulling
overnight into the morning hours. Breezes will further slacken
towards late week as the high continues to loosen its grip.
