These are swift moving channels of water that are difficult to swim against. Strong currents frequently accompany high surf and rapid tide changes and can be recognized as a turbulent channel of water between areas where waves are breaking. When caught in a strong current -- Try to keep a level head, i.e., don't panic! Wave one or both hands in the air, and scream or call for help. Swim diagonally across the current, not against it. Please heed all posted warnings! Your life could depend on it!
