Episode Narrative Strong thunderstorms brought penny and nickel sized hail to near Waterville, Entiat, and Omak. The strongest storm occurred on the Waterville Plateau where significant rain damage from flash flooding as well as nickel size hail fell. Heavy rain with 2.25 inches in two hours was reported four miles northeast of Waterville which washed out a road. The headwaters of Douglas Creek took out fences and parts of Road 11 NW. The water was 10 feet deep in spots. Some fields received a complete wheat loss. Meanwhile, heavy rain on the Nahahum fire north of Cashmere resulted in a shoulder being partially washed out on Nahahum Canyon Road between milepost four and five.
