Recent rainfall across the region has increased soil moisture to high levels across western Washington. Heavy rain has occurred over the Olympic Peninsula this morning and continues to push inland. Additional rainfall of 2 to 6 inches is expected through Sunday. This amount of rain will put extra pressure on soil instability, leading to an increased threat of landslides. Areas above 5000 feet in elevation will see some of the precipitation as snow and not be as affected.
