A week-old wildfire in southern California picked up steam late on Thursday and early Friday as firefighters in the drought-stricken state struggled to find enough water to contain the blaze. The fire has so far consumed about 40 square miles of the San Bernardino mountains, about 90 miles east of Los Angeles. It is one of several fires spreading along the west coast this week, and one of 2,500 fires to break out this year alone in California. The wildfires have been exacerbated by the historic drought in western states. Almost 70% of California is considered to be in “extreme to exceptional drought”, according to the National Drought Mitigation Center.
