Previous rainfall of 2-10 inches or more over the past 24 hours has Resulted in high levels of soil moisture around western
Washington. Heavy rainfall of 2-5 inches more in 24 hours is Expected. This amount of rain will put extra pressure on soil
Instability leading to an increased risk of landslides.
The usgs rainfall index...rainfall threshold...and rainfall Intensity threshold are all currently exceeded and will be for the
Duration of the heavy rain. All of these together have elevated The landslide risk to high risk
Landslides have been occurring in a number of locations in Many counties throughout western Washington.
Cumulative rainfall over the last three weeks have wetted soils To the point where they are above the usgs landslide index. When
Cumulative rainfall over the previous three days and previous Eighteen days combine to exceed the usgs landslide cumulative
Threshold index...rainfall induced landslides are possible during Intense rainfall or when rainfall amounts exceed two inches in 24 Hours. A diminishing risk of landslides will continue for several Days after the rain ends.
While the usgs rainfall thresholds were designed for the Seattle Area of the Puget sound...most of the lowlands of western
Washington are similarly susceptible to landslides caused by wet Soils. Areas most susceptible to landslides under these conditions Are steep coastal bluffs and other steep hillsides.
