Huge Duststorm Hits Phoenix (Video)

A massive 50-mile-wide dust storm blew through Phoenix late on Tuesday; videos show a gray wall sweeping across the city. Winds reached 60 miles per hour, severe thunderstorm warnings were issued, and visibility was so reduced that flights to Phoenix from Los Angeles and Las Vegas were canceled until 9 p.m. Tuesday. The high winds are expected to continue for several days.

All I can say is, Wow!
