Episode Narrative Spokes of energy rotating around an upper-level low digging down the Washington Coast tracked over Eastern Washington during the afternoon of July 15th. The mid level wave encountered moist, unstable conditions in place resulting in scattered thunderstorms across Northern Washington. A few storms matured into severe storms producing damaging winds and large hail. Several other storms brought torrential rains to the area. In Okanogan County, in addition to severe winds and hail, the heavy rainfall resulted in numerous small debris flows and flash flooding along Highway 97.
Event Narrative Highway 97 north of Malott, WA was blocked by debris at milepost 279. Flash flooding clogged a culvert and washed out a portion of the roadway. Railroad trestles were also taken out at this milepost.
