Overview
- Alerts are active from late Monday night through Tuesday with county-specific end times ranging from early afternoon to evening.
- California warnings cover Coastal Del Norte, northern and southwestern Humboldt, and Mendocino because of an increased threat of sneaker waves.
- Oregon's Douglas, Coos, and Curry counties face a moderate risk through early Tuesday afternoon, with guidance to stay off rocks and jetties and remain out of the water.
- The NWS notes sneaker waves can follow long quiet periods, rush at least 150 feet upshore, and move heavy logs or rocks that can knock people over or trap them.
- Safety advice includes keeping well back from the surf, avoiding steep beaches, and never turning your back on the ocean while conditions remain hazardous.
