 It's hot, dry, and windy across much of California, and wildfires are exploding across the state. Up and down California is feared with temperatures hitting over 100 degrees. Wildfires are again breaking out. Fires in Napa County and another near the town of Oroville have kept firefighters busy. In parts of northern California, Pacific Gas and Electric has shut off power to prevent wildfires because of the heat and wind, causing concerns that fire activity could be explosive.
