ENTIAT, Wash. - A wildfire burning west of Entiat grew to 10,100 acres Thursday, fire officials said. That nearly double the size from earlier in the morning.

There are 109 residences under a mandatory Level 3 evacuation and another 122 under a Level 2 evacuation, which means residents should be ready to head out.

Just over 400 firefighters are battling the fire Thursday, up from 250 on Wednesday.

A 30-mile stretch of US-97A is now closed from Wenatchee at milepost 201 to milepost 230.5 south of Chelan. Motorists going between Wenatchee and Chelan can use U.S. 2 on the east side of the Columbia River.

Drivers were also advised to use US-97 via Orondo, though Chelan County officials say visibility is bad due to thick smoke and advise motorists to drive slow.

A house fire Tuesday started the wildfire in the Mills Canyon area which quickly spread to about 8 square miles. Fire spokesman Mick Mueller says about 250 firefighters were aided by air tankers dropping retardant and helicopters dropping water; the fire remains zero-percent contained.
