PHOENIX (AP) - Officials say lightning is responsible for sparking more than a dozen wildfires in the area known as the Arizona Strip near the Arizona-Utah border.
Fire management officers say 13 fires are burning in the area after several storms moved through Wednesday afternoon.
Two groups of fires are burning south of St. George, Utah, in Arizona.
One group of blazes has burned about 28 square miles, and another has burned about 7 square miles.
Several ranching structures, like outbuilding and barns, are threatened.
Road closures in the area were pending Thursday afternoon.
No evacuations have been reported.
