A wildfire that was started by lightning Friday grew to more than nine square miles of grass on Monday near Malaga.
Fire managers say the Milepost 10 Fire threatens a power transmission line. Residents of 78 homes were told to evacuate, but spokesman Rick Isaacson told The Wenatchee World many chose to stay. The Red Cross set up a shelter in a Wenatchee church.
The fire is about eight miles south of Wenatchee, burning in dry grass above the Columbia River.
Meanwhile, mudslides were a problem in the Colockum area south of Malaga. Chelan County Emergency Management said three homes may have been pushed off their foundations.
Mudslides also closed Highway 20 east of Rainy Pass on the North Cascades Highway.
Forecasters expected more thunderstorms Monday.
