Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
429 AM EDT Thu Sep 19 2024

.SYNOPSIS...Light and often variable breezes will continue
through the remainder of the week due to persistent troughing near
the Atlantic Coast. Expect higher winds and seas in and around
thunderstorms. The troughing will meander southeast to southward
this weekend and into early next week and deepen while ridging
builds in across the southeast. Confidence in the extended
forecast is very low due to uncertainties with this evolution, as
well as expected formation of a low in the northwestern Caribbean
Sea.
