Four homes have been lost to the Flat Fire as it continues to threaten nearly 4,000 homes in Deschutes and Jefferson counties.

The wildfire raging in Central Oregon has destroyed four houses and about half a dozen other buildings, the Deschutes County Sheriff’s Office said on social media late Sunday. The Flat fire, about 2 miles northeast of Sisters, has scorched about 22,000 acres and remains 0% contained, fire officials said.

The largest wildfire in Oregon remains under a red flag warning through Aug. 26, meaning it's expected to continue growing in the foreseeable future.
