A haboob, a type of dust storm that hits desert areas during the monsoon season, swept through the Phoenix area on Aug. 20. The storm, though intense, was fairly short-lived, as a downdraft from seasonal thunderstorms pushed dry dust in a cloud across the area.
"They act like mini cold fronts with the dust layer spreading out in front of a thunderstorm," said AccuWeather.com Meteorologist Ken Clark. "These can bring extremely low visibility and even cause traffic accidents and disrupt air travel at airports they affect."
These local residents captured the event on social media.
