Giant Dust Storm Moves Through Phoenix Area

PHOENIX (AP) - For the second time in less than two weeks, Phoenix has been enveloped by a giant dust storm called a haboob.

The National Weather Service says the dust towered 3,000 feet high and winds gusted to 40 mph. Visibility in fell below a quarter-mile delaying flights at Sky Harbor International Airport.
The storm began to clear within an hour after arriving.

The earlier haboob brought a mile-high wall of dust that knocked out power for hundreds of people and turned swimming pools into mud pits.

Weather experts say haboobs only happen in Arizona, the Sahara desert and parts of the Middle East. All places where it's dry and sandy.
