Heavy rainfall over the past week and a prediction of up to three more inches Friday led the National Weather Service to issue a landslide warning to Whidbey Island on Wednesday.
According to a weather statement sent out Wednesday, between one and six inches of rain fell over the past three days, which adds pressure to soil instability.
"Cumulative rainfall over the last week has soaked soils to the point where the Washington landslide risk level is at elevated levels and increasing," said the statement. "The predicted rainfall might be enough to act as a trigger for landslides."
Steep coastal bluffs, like those around Whidbey Island and other steep hillsides are most susceptible, according to the statement. San Juan County, Western Whatcom County, the southwest interior, the east Puget Sound lowlands, Western Skagit County, Everett, the Seattle Bremerton area, Tacoma, Hood Canal, and the lower Chehalis Valley were also areas are concern in the statement.
