Hikers and bikers in the White Tank Mountain Regional Park were evacuated from the trails and park is temporarily closed after a wildfire broke out in the area early Thursday evening. The Tank Fire has burned about 35 acres and is 40 percent contained on the southeast side of the park. The Surprise Police Department said White Tank Park is temporarily shut down while crews try to put out the fire. The Arizona Department of Forestry and Fire Management said the flames were caused by humans but not sure exactly how yet. One of our viewers who was less than a mile away described seeing heavy brown smoke, and then seeing red/orange flames across the top of the peaks. No injuries have been reported from the fire.
