Rip currents are the most threatening natural hazard along our
coast. They pull victims away from the beach. The United States
Lifesaving Association has found that 80% of the rescues
effected by ocean lifeguards involve saving those caught in rip
currents.
A
rip current is a seaward moving current that circulates water
back to sea after it is pushed ashore by waves. Each wave
accumulates water on shore creating seaward pressure. This
pressure is released in an area with the least amount of
resistance which is usually the deepest point along the ocean
floor. Rip currents also exist in areas where the strength of
the waves are weakened by objects such as rock jetties, piers,
natural reefs, and even large groups of bathers. Rip currents
often look like muddy rivers flowing away from shore.
Rip
currents are sometimes mistakenly called "rip tides"
or "undertows." These are misnomers. Rip currents are
not directly associated with tides and they do not pull people
under.
Try
to avoid swimming where rip currents are present, but if you
become caught in a one, swim parallel to the shore until the
pull stops and then swim back to shore. If you are unable to
return to the beach, tread water and wave for lifeguard
assistance.
Stay
at least 100 feet away from piers and jetties. Rip currents
often exist along the side of fixed objects in the water.
Be
aware of ocean conditions. Lifeguards are trained to identify
potential hazards. Ask a lifeguard about the conditions before
entering the water.
