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.

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.

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