(CNN) A fire in the Tucson area has grown to thousands of acres and is threatening hundreds of homes. The Bighorn fire was sparked by lightning in Pima County on June 5. By late Thursday, the fire had grown to 6,200 acres and was 10% contained, according to the Coronado National Forest. More than 6 million people across Nevada, Arizona, Utah and eastern California are under red flag warnings through Friday evening. Across the Southern Rockies and Southern High Plains there is a chance for dry thunderstorms where lightning could threaten to start new fires, Brink said.
