* Low Risk of rip currents - Strong currents can still occur near
jetties and reef channels. 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. If caught in
a rip current, swim parallel to the beach rather than against the
current.
