Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
426 PM EDT Sat Jun 22 2024

.SYNOPSIS...The interaction between 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 becoming
gentle late this evening. Moisture pulled into our area via the
low to the west will lead to periods of unsettled weather for the
rest of the 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.
