2 Arizona Towns Empty as Wildfire Approaches Power Lines

Fire crews worked through the night to protect several Arizona mountain communities from a growing forest fire that has forced thousands from their homes and threatens transmission lines that supply electricity as far east as Texas. The 607-square-mile blaze, the second largest ever in Arizona, is expected to reach the power lines as early as Friday. If the lines are damaged, hundreds of thousands in parts of New Mexico and Texas could face rolling blackouts. Meanwhile, crews were hopeful that they could slow the fire Thursday if weather predictions hold true. After a few days of driving winds, there was no high-wind warning issued for Thursday.
