In southern Arizona, a fire covers around 29,000 acres of the Coronado National Forest south of Tucson, the Arizona Daily Star Friday. There are more than 800 people fighting the fire that was caused by a lightning strike June 7. On Friday Arizona Gov. Doug Ducey declared a state emergency and authorized the use of $200,000 of emergency funds to fight the fire.

“We thank the many brave men and women who have stepped up and responded to wildfires around Arizona,” Ducey said in a statement. “I’m issuing today’s declaration to make sure they have every resource needed to do their jobs and protect our communities. Public safety is our top priority, and we will continue to coordinate with state and local emergency response officials to keep Arizonans safe."

CNN said 2017 already has outpaced the 10-year average for wildfire damage. As of Thursday, more than 2.5 million acres of the U.S. had burned, around 1 million more than the average at this point in the year. The total number of wildfires is down slightly, however. There had been 27,943 wildfires as of Thursday. The 10-year average is 30,365.
