Episode Narrative A nearly stationary upper level low pressure area parked near Brookings, Oregon brought abundant moisture across eastern Washington. This combined with daytime heating to produce a few severe thunderstorms and locally heavy rainfall. The heavy rainfall caused flash flooding and landslides in several areas. The upper level low moved north away from the area late on July 20.
Event Narrative Radio operator was at the Table Rock Fire Lookout.
