Episode narrativeepisode_narrativeA closed upper-level low over the Washington Cascades delivered a low shear but unstable environment. Sufficient atmospheric moisture, characterized by precipitable water values near one inch, was already in place. A combination of afternoon heating and lift along spokes of energy pivoting around the main low sparked numerous rounds of wet thunderstorms between the early morning hours of August 13th through morning of the 15th. The heaviest storms were delivering around one inch of precipitation over a thirty to forty minute time period. Several debris flows were observed in areas where the storms moved over burn scars.
Event narrativeevent_narrativeHeavy rain caused a mudslide at Thimbleberry Creek at the 7.5 mile marker on Stehekin Valley Road. Three large culverts and creek channels are filled with debris. The water became rerouted around the debris and along the road to a culvert 1000 feet down valley. A second smaller slide was at the No Named Creek. A third slide is at mile 9.2 where debris slid to a barn and corral at a ranch.
