…HEAVY RAINFALL THURSDAY AND FRIDAY WILL LEAD TO AN INCREASED THREAT OF LANDSLIDES IN WESTERN WASHINGTON…

Periodic rainfall over the last few days and few weeks has increased soil moisture to moderate levels across western Washington. Heavy rainfall of one to three inches over the lowlands and foothills and 5 to 8 inches over the Olympics is expected Thursday through Saturday. This amount of rain will raise the soil moisture to high levels and put extra pressure on soil instability, leading to an increased threat of landslides during that period.
