Rip current risk today: low

The flag in the picture is the colour of the forecast's risk (green low, yellow moderate, red high), not a flag raised on the beach.

A rip current is a narrow stream of water running out from the shore through the surf, often where fewer waves break. Caught in one, swim across it, along the shore, then back in.
