Windy spring storm sweeps through Calif., Arizona

Powerful winds raked much of California on Monday, toppling trees, spreading wildfires, causing scattered power outages, whipping up blinding dust storms, and sending waves crashing ashore as a vigorous spring weather system swept through the state on its way across the West. Rising winds were reported in Arizona, where 34 miles of Interstate 40 near Winslow were closed to traffic. In Phoenix, blowing dust obscured the mountains surrounding the city, and at least four people were injured in a pileup when two semi-trucks jackknifed in a dust storm on I-10 in southern Arizona. The injuries were not life-threatening.
