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.

Firefighters battling the Oregon Flat Fire, which has so far torched nearly 22,000 acres, could face setbacks if the latest weather conditions shift, officials cautioned Monday. The raging blaze, which is only 5% contained, has destroyed homes and buildings. Thousands of families have been forced to evacuate.

The Flat Fire has burned 21,971 acres across Jefferson and Deschutes counties in central Oregon. Fire managers tell KATU News that the fire is 5% contained.
