A thunderstorm that rolled through the Wenatchee Valley Saturday afternoon dumped heavy rain that led to a mudslides and some evacuations in South Wenatchee.
The flash flooding and mudslides did severe damage to at least three homes on Boodry Street in East Wenatchee.
Chelan County Emergency Management Director, Kent Sisson says the extremely heavy rain caused mud and debris flows in the Squilchuck Canyon, Pitcher Canyon and Halverson Canyon areas. Storm drains and culverts became overwhelmed quickly as water and mud began running down the roadways.
A culvert which diverts water under the lower Squilchuck Road, began eroding the downslope hillside located above Boodry Street just south of the city limits.
The force of the water began creating a deep channel in the earthen slope and which forced a massive amount of rock and mud down the hillside and into a development of single-wide mobile homes.
Deputies and Wenatchee Police officers responded and began evacuating the development. A river of mud, rock and other debris impacted the north side of three mobile homes nearly to the roof lines.
Children were carried out of one home by deputies and Wenatchee police officers. Three of the mobile homes are now deemed uninhabitable. The flow of water, rock and debris began to slow by 6:00pm, but more rain was predicted during the evening.
Residents of 16 homes in the area were advised they should stay out of the area until the storm completely subsides. Chelan County Public Works engineers and road crews responded and began assessing the slope and clearing the affected roadways.
Chelan County Emergency Management said the Red Cross is on standby to provide emergency shelters, if needed.
The damage on Boodry Street is not far from where a late June rainstorm created a sinkhole that has yet to be repaired on South Wenatchee Avenue.
The Weather Service had earlier issued a flash flood warning for much of the region as the storm approached.
Highway 2 east of Waterville was shut down for about a half hour about 7 p.m. after being completely blocked by mud and debris, said Trooper John Bryant of the Washington State Patrol
The thunderstorm also delayed the start of the Avett Brothers concert Saturday at the Gorge Amphitheater for about an hour.
The Grant County Sherifrf’s Office had advised concertgoers to shelter in their vehicles during that time.
The severe weather day included a funnel cloud spotted east of Ellensburg.
