VIDEO: More than 800 lightning ground strikes have caused wildfires to spark across Arizona so far this year.
Some of those fires are the Benchmark, Clair, Bartlett, and Wally fires. The Skeleton Fire has burned more than 21,000 acres and is uncontained as of Monday night. The Sand Stone Fire has burned over 27,000 acres and is 82% contained.
As the sun was setting on Monday night, you could see the separate pockets of smoke coming from areas within the Tonto National Forest.
More than nine wildfires were started by Sunday night's monsoon storm, stretching fire crews thin during a busy fire season. "A lightning strike can actually be hotter than the surface of the sun," said Alex Young, lead meteorologist with the National Weather Service in Phoenix.
