WHAT IS A RIP CURRENT? Rip currents are powerful currents which can overwhelm even experienced swimmers. They have the ability to pull a swimmer away from the safety of the shore. Panic and subsequent drowning can result.
Rip currents form when water rushes out to sea in a narrow path. This happens when there is a wave break in a sandbar nearshore or the current is diverted by a jetty or other barrier. Rip currents can extend 1,000 feet offshore, reach 100 feet in width and travel up to 3 mph. Some are present a few hours; others are permanent. Rip currents are more prevalent after storms. Polarized sunglasses cut glare and help to spot rip currents.
TELLTALE SIGNS OF RIP CURRENTS
A difference in water color - either murkier from sediment or darker from greater depth.
A difference in the waves - larger, choppier waves in the rip current; smaller, calmer waves in front of the bar.
Foam or objects moving steadily seaward.
An offshore plume of turbid water past the sandbars.
WHAT TO DO If you're caught in a rip current, don't panic or swim against the current. Swim parallel to shore until you are out of the current. Rip currents are rarely more than 30 feet wide. If you can't break out of the current, float calmly until it dissipates, usually just beyond the breakers. Then swim diagonally to shore. If you don't swim well, stay in wading depths and watch for sudden drop-offs.
