Episode narrativeepisode_narrativeMoist, southerly flow ahead of an area of low pressure trickling northward along the Oregon Coast created a moist, unstable environment over Central Washington. Shortwaves ejecting from the shortwave trough supplied the necessary lift to initiate numerous strong thunderstorms across the East Slopes of the Cascades and portions of the Western Columbia Basin. These storms developed during the evening and overnight hours of August 9th and persisted well into the morning hours of August 10th. Storms dissipated around midday then afternoon heating and a second shortwave triggered another round of strong storms during the afternoon and evening hours of the 10th. The main threat with these storms was high rain intensity and flash flooding, however one line of storms also delivered damaging winds.
Event narrativeevent_narrativeHeavy rainfall led to a debris flow across Number Two Canyon Road roughly from mile post three to the end of the pavement around 0000 PST. The slide left half to one foot of mud and debris, including rocks, over the roadway rendering the road impassible. The Number One Canyon Near Wenatchee Rain Gauge (NOOW1) received 0.29 of rainfall over a span of 29 minutes. Runoff incised ditches up to four feet in diameter exposing utilities.
