Emergency responders are dealing with flash flooding throughout the region that has swamped at least three highways.
Water and mud has covered Highway 97A near Entiat and it was closed about 4:30.
A U-Haul truck and a dump truck were stuck in the mud, said Trooper John Bryant of the Washington State Patrol.
The mud is up to 2-feet-deep in some places, Bryant said.
Even worsen, Highway 971, South Lakeshore Drive along Lake Chelan is closed in both directions after mud, dirt and rock came pouring down Slide Ridge.
The Slide Ridge landslide buried the roadway in 7-to-8-feet of mud, Chelan County reported.
Meanwhile, State Route 2 east of Waterville was closed after a flash flood covered that highway with mud.
That road was fully blocked, but was reopened at about 4:10 p.m.
The flash flooding came earlier than the Weather Service had predicted, Bryant said.
The 97A flooding is near Earthquake Point about five miles north of Entiat.
