The Bootleg Fire, a fast-moving wildfire in southern Oregon, has burned more than 200,000 acres, making it the largest of dozens of blazes across the United States, officials said Tuesday.

The Bootleg Fire, which began more than a week ago and remains zero percent contained, has set off a wave of evacuations and prompted more than 130 engines to respond, according to fire officials.

The National Weather Service has issued a red flag warning for areas in southwest Oregon, indicating critical fire weather conditions, through 8 p.m. on Wednesday.

The wildfires in the West have been fueled by extreme drought conditions, single digit humidity and high temperatures.

The Bootleg Fire has already destroyed several homes in Klamath County, where officials ordered evacuations.
