This warning includes beaches at Red Arrow Park, Neshotah Beach and Point Beach. The warning is for high wave action, structural currents, longshore currents, and rip currents. Structural currents form along piers and can sweep you into deeper water.

Rip currents are powerful channels of water flowing quickly away from shore and can sweep you into deeper water.
