from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards and the beach patrol.
Pay attention to flags and posted signs.

Don't fight the current. Swim in a direction following the
shoreline. If unable to escape, face the shore and call or wave
for help. If tired, float or tread water until out of the rip
current.
