Portions of western Washington state have experienced a month’s worth of rain within the past few days, causing historic flooding, damaging mudslides and more than 100,00 people facing potential evacuations.

SKAGIT COUNTY — The sun set Thursday over the soggy and worried people of Western Washington while the fast-running Skagit River, full of sediment and debris, swelled.

A century-old Skagit River dike is holding as 75,000 residents remain under evacuation orders. Officials warn flood risks will continue into Saturday morning.

The Burlington Police Department and Skagit County Emergency management issued a city-wide evacuation this morning, after initial reports that the Slough, part of the Skagit River watershed, has jumped its banks. The City has nearly 10,000 residents.

The Skagit River is predicted to crest at more than 47 feet near the town of Concrete, north of Seattle, 15 inches above the threshold for a major flooding event.

Major flooding is expected in Skagit County from Wednesday afternoon through Friday evening. According to a news release from the county Department of Emergency Management, the Skagit River is forecast to crest at 40.

About 78,000 residents of a major agricultural region north of Seattle were ordered to evacuate the Skagit River’s floodplain, officials said
