A sneaker wave knocked down a woman from Portland on the beach at Roads End in Lincoln City, according to the Lincoln City News Guard.

She was with three others who were able to remain free of the wave's power.

The injured woman was taken to a hospital with a non life-threatening leg injury, the News Guard reported. Her name and condition was not available.

Another Tillamook County woman was almost knocked over by a storm surge of water and wood that crashed up a drainage ditch as she walked along off the beach. It happened before noon as Missy Syfers walked to work along railroad tracks near Highway 101 in Rockaway Beach.

“The water just came up and right to the railroad tracks, I walk here every day to work. It scared and and I ran”, said Syfers.

The Shorewood RV Park nearby suffered damage to some beachfront units from waves that crashed in through a pathway at one end of a rip rap rock barrier. Workers were fixing the damage Thursday. Nobody was hurt.

The parks department closed access to the beach, along with beaches in Fort Stevens and Newport.

The National Weather Service issued a Coastal Flood Warning for Thursday in Clatsop, Tillamook and Lincoln counties.

Breaking waves of 35-45 feet were expected, according to the National Weather Service, which sent water further up beaches and jetties.
