Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
436 PM EST Sat Nov 15 2025
.SYNOPSIS...High pressure centered over the Southeast U.S. will
continue to move southward throughout the rest of the weekend.
This will promote light to gentle breezes. Due to the weak flow,
there may be a period of light and variable breezes Sunday through
Monday, mainly in the afternoons. Another high pressure system
will traverse across the eastern United States early next week
while slowly strengthening. This will allow for freshening
northeast to east breezes for the middle and latter part of next
week.
