LANDSLIDES IN WESTERN WASHINGTON…

moisture to high levels across western Washington. Heavy rainfall of
1-2 inches additionally is expected through early Saturday. This
amount of rain will put extra pressure on soil instability, leading
to an increased threat of landslides. At least one mudslide has
