Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
424 PM EDT Fri Jun 21 2024

.SYNOPSIS...Interaction among low pressure off the east coast of
Florida, high pressure centered north of Bermuda, and broad low
pressure in the vicinity of the Yucatan Peninsula will result in
gentle to moderate east to southeast breezes over the next few
days. Moisture pulled into our area via the low to the west will
result in waves of unsettled weather this weekend. High pressure
building over the North Atlantic early next week will result in
light to gentle southeast to south breezes and a return to near-
normal rain and thunder chances.
