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.

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

Ten structures — including four homes — have been destroyed by a wildfire sweeping through central Oregon, where thousands of residents remained under evacuation orders on Monday, while a blaze in Northern California wine country has so far spared some of the state's most famous vineyards.
