Expires: Sat May 2, 2026, 5:00 AM
* WHAT...Moderate risk of sneaker waves expected. * WHERE...Beaches of Curry, Coos, and Douglas counties. * WHEN...From 11 PM PDT Saturday evening through 11 AM PDT Sunday morning. * IMPACTS...Sneaker waves can run up significantly farther on beaches than normal, including over rocks and jetties. These waves can suddenly knock people off of their feet and sweep them into the ocean. The waves can also move logs or other objects which could crush or trap anyone caught underneath. * ADDITIONAL DETAILS...A short period northwest swell and a building long period northwest swell may combine their energy to produce dangerous surges. The risk will be highest around sunrise on Sunday morning. * View the hazard area in detail at https://www.wrh.noaa.gov/map/?wfo=mfr
Avoid climbing on rocks and jetties. Stay away from the ocean and remain out of the water to avoid hazardous conditions.
