California's Klamathon Fire "exploded" to cover 30,000 acres by Sunday night, tripling in size from Friday night and crossing the state line into Oregon. The blaze has already killed one person and destroyed 15 buildings. It was just 25 percent contained as of Sunday, and authorities said the Klamathon fire is exhibiting "extreme fire behavior with movement in multiple directions." Additional fires are raging in elsewhere in California, particularly in the hot and windy southern region of the state. Thousands of people have been evacuated as temperatures climb well over 100 degrees.
