rip currents

Definition

A strong surface current of short duration flowing seaward from the shore. It usually appears as a visible band of agitated water and is the return movement of water piled up on the shore by incoming waves and wind. With the seaward movement concentrated in a limited band its velocity is somewhat accentuated. A rip consists of three parts: the feeder current flowing parallel to the shore inside the breakers; the neck, where the feeder current converge and flow through the breakers in a narrow bank or "rip"; and the head, where the current widens and slackens outside the breaker line. A rip current is sometimes incorrectly termed a rip tide
