| Episode Narrative | Slow moving thunderstorms containing very heavy rainfall led to flash flooding across portions of Central and Eastern Washington. The west side of Wenatchee was hardest hit as a very slow moving thunderstorm brought 0.85 inches of rain in 45 minutes. Road washouts were reported on Number 1 and Number 2 Canyon Roads. Manhole covers were blown out in Downtown Wenatchee with standing water on some roads. Four miles south of Wenatchee on Squillchuck Road, the heavy rain resulted in a mudslide. Flash flooding resulted in water threatening homes, with several reports of house flooding. Mud inundated indoor tennis courts at an athletic club. Another thunderstorm brought heavy rain just north of Entiat, sending a mudslide onto Highway 97A between mileposts 220 and 222. The mud was up to six inches deep with two cars towed from the mud. The road was closed during the night and opened the next day. Another slow moving thunderstorm in Lincoln County resulted in road washouts along Highway 23 between Sprague and Harrington. |
