The National Weather Service in Seattle has issued a Special Weather Statement due to the increased threat of landslides for the lowlands from Snohomish to Jefferson Counties southward. Forecaster say that as the snow melts and rainfall continues, the soil saturation rises and with it the chance of landslides. The landslide threat will increase through the week and expand northward to the Canadian border and upward in elevation into the foothills as warmer weather continues to move into the region.

Melting snow is very efficient at increasing soil moisture and is not well represented in the landslide indices such that the threat is higher than the indices suggest. Additional rain today through the weekend will put extra pressure on soil instability, leading to further increased threat of landslides.

Areas above around 1500 feet in elevation will see mostly snow and freezing temperatures and will not be affected.
