Highway crews are trying to clear mud and debris that washed onto roadways when heavy rain fell on land scarred by wildfires in north central Washington.

The Washington Transportation Department says sections of Highway 20 and Highway 153 near Twisp that were hit Thursday night remain closed Friday morning.

Spokesman Jeff Adamson in Wenatchee and National Weather Service meteorologist Steven Van Horn in Spokane say there were reports of some motorists stranded and homes being washed off their foundations, but there are few specifics.

The Weather Service says more slow-moving thunderstorms are expected to roll through the area again Friday evening, so there's a flash flood watch in effect.
