Florida's east coast will experience rough surf arriving as early as Monday. There is a high risk of dangerous rip currents with wave heights reaching between 6 and 10 feet.

It is expected to reach Jacksonville’s latitude about early Wednesday, resulting in some rough seas and surf at area beaches next week.
