500-acre wildfire in Grant County forces mandatory evacuations, knocks out power to Quincy

QUINCY, Wash. -- A fast-spreading 500-acre wildfire forced mandatory evacuations northeast of Quincy and knocked out power to the city Wednesday night, authorities said.

The Washington Fire Marshal said at least 10 homes were under mandatory Level 3 evacuations, and state mobilization had been approved to help battle the Monument Hill Fire.

"Homes and crops threatened," the state Fire Marshal tweeted about the "growing" wildfire.

The Grant County Sheriff's Office said a Red Cross shelter was opening at midnight Quincy High School for those homeowners who had to evacuate.

The Grant County Sheriff's Office said on its Facebook page, "Level 3 (evacuation) means you are in immediate danger. Load your family and pets into your vehicle, and GO NOW. There will be no further warnings!"
