As of Monday morning, the blaze had charred about 32 square miles (83 square kilometers) of grass and chaparral and blanketed the area with a thick cloud of dark smoke.

Out-of-control wildfires in the foothills of a national forest east of Los Angeles and in a recreational area south of Reno, Nevada, threatened buildings and forced hundreds of residents to flee amid a days-long heat wave of triple-digit temperatures.

The Davis Fire south of Reno has burned over 3,000 acres and triggered evacuations, with fire crews expecting flare-ups to last through Sunday due to windy conditions.
