For the High Rip Current Risk, through late Thursday night. * IMPACTS...For the High Surf Advisory, high waves that can wash over jetties and sweep people and pets onto jagged rocks. Rough surf may also knock you down. Large breaking waves will result in localized beach/dune structure erosion and dangerous swimming conditions. For the High Rip Current Risk, rip currents can sweep even the best swimmers away from shore into deeper water, where it becomes difficult to return to safety.

A High Surf Advisory means that high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions. There is a high risk of rip currents. Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as groins, jetties and piers. Heed the advice of lifeguards, beach patrol flags and signs. If you become caught in a rip current, yell for help. Remain calm, do not exhaust yourself and stay afloat while waiting for help. If you have to swim out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current as you will tire quickly.
