VIDEO: Sand Storm/Dust Cloud ‘Haboob’ Invades Phoenix, Arizona


An amazing video shows a wall of dust moving through the city of Phoenix in Arizona.

Sandstorms like this happen during the region’s monsoon season, which is underway. The sandstorm or ‘haboob’ occurs over desert land and can reach thousands of feet into the air, spurred by strong winds. The dense cloud dramatically reduced visibility, grounding flights at a major airport and leaving thousands without electricity. The dust storm originated in Tucson.


The massive Phoenix dust cloud was about 5,000 feet when it arrived in Phoenix, but radar images indicated that it reached heights anywhere from 8,000 to 10,000 feet as it approached the city. The sandstorm was estimated to be about 50 miles wide in some areas, according to KSAZ-TV.
