A massive dust devil spun up in the desert Southwest on Tuesday and at least one motorist got the twister on video.
Lance Brown was driving in Scottsdale, Ariz., when the powerful whirlwind spun dirt and debris high into the sky.
Arizona has been suffering widespread severe and exceptional drought, so there was plenty of dust to go around.
Dust devils form when hot air near the surface rises quickly through cooler air above it. That forms an updraft, similar to thunderstorms, and creates the spinning column of air.
