Always have a flotation device with you in the water. Moderate Risk of rip currents - Wave conditions support stronger or more frequent rip currents. Always have a flotation device with you in the water. High Risk of rip currents - Large waves will produce strong rip currents, especially along narrow reefs and beaches. Rip currents will be life threatening. If caught in a rip current, swim parallel to the beach rather than against the current. $$
