* WHAT...A high risk of sneaker waves is expected today with a moderate risk tonight into Monday. * WHERE...Beaches along Curry, Coos, and Douglas Counties. The highest risks will be to west-facing beaches. * WHEN...Through Monday afternoon. * 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 quickly pull them into the cold ocean waters, resulting in serious injury or death. Waves may also lift driftwood logs, trapping anyone caught underneath. * View the hazard area in detail at https://www.wrh.noaa.gov/map/?wfo=mfr
