Phoenix is left blanketed in grit after the Arizona city was enveloped by a massive sand storm.


A towering wall of dust blew over the city of Phoenix on Monday caused by thunderstorms in western Arizona.

Visibility in the area dropped below a quarter of a mile as winds of up to 60mph downed power lines and trees.

Arizona's monsoon season lasts from June to October. In recent years it has produced massive dust storms, known as "haboobs", sometimes stretching over 100 miles.
