July 5, 2006 Slide Ridge Flash Flood Event
Chelan County, WA
|
| During the afternoon of July 5, 2006, an outbreak of severe thunderstorms along the east slopes of the Cascades resulted in significant flash flooding in and near Lake Chelan. The radar loop above depicts the track of several strong to severe thunderstorms between 400 pm PDT and approximately 630 pm PDT. Radar estimated between 2.5 and 3.0 inches of rain within about a 2 hour time span (see radar storm total precipitation image below). Runoff from the very heavy rain resulted in a significant rock/debris slide along Slide Ridge south of Lake Chelan. The slide damaged portions of South Lakeshore drive between Lake Chelan State Park and Twenty-five Mile Creek State Park. |
