Incredible massive rolling dust storm. A massive dust storm enveloped areas of Arizona on Tuesday night, causing low visibility and delaying flights in and out of the state's largest airport.
The violent dust or sandstorm called a haboob typically occurs over desert land and can stretch thousands of feet high, according to the National Weather Service.
It prompted the Federal Aviation Administration to issue a ground stop of about an hour and 15 minutes at Phoenix's Sky Harbor Airport.
