Officials are warning of strong swells in Seaside on Thursday.
The swells are expected to begin near midnight and peak midday Thursday, creating large waves and beach erosion, according to the National Weather Service. Tides likely will reach as high as 10 1/2 feet and breaking waves of 35 to 45 feet may occur at sea.
Flooding is expected in low-lying areas. The event will likely be similar to floods caused by high swells in the area in December of 2015 that impacted structures. Willapa Bay, Nehalem, Tillamook and Florence will also be affected.
“Structures and roads located immediately at beach level will potentially be flooded or impacted by debris,” according to a press release from the weather service. “Many cove access beaches, jetties, and rocky outcroppings will be covered by deep water.”
Residents are advised to prepare property and avoid beaches and areas that may be cut off to escape routes.
