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.

Ten structures — including four homes — have been destroyed by a wildfire sweeping through central Oregon as thousands of homes in the state and in Northern California wine country remained under evacuation orders Monday.

More than 3,900 homes in Oregon were under threat because of the Flat fire, which was one of many wildfires burning in the West, amid hot weather.
