The National Weather Service has issued a weather alert for potential waterspouts from Newport to Long Beach, Washington, through Sunday morning.
Showers and isolated thunderstorms across the region this weekend could bring the potential for a few waterspouts along the coast starting later Saturday and continuing into Sunday. If a waterspout does form, it could move onshore as a brief tornado before dissipating, the weather service said.
Waterspouts are tornadoes that form over water, or move from land to water and are often accompanied by high winds and seas, large hail and lightning.
Residents are advised to seek shelter if threatening weather approaches.
Tornadoes are uncommon but not unheard of on the North Coast. A tornado resulted in property damage in Manzanita in October 2016.
