Fire danger is back down to critical after reaching extreme levels on Monday, but red flag warnings continue across six states in the Southwest, from Nevada to Oklahoma.

       More than a dozen wildfires continued to burn on Tuesday across the region. The San Rafael fire in Arizona is 12% contained over 11,000 acres. The Hermit Creek and Calf Canyon fires are 39% contained over 200,000 acres.
