Arizona dust storm is coming back
Also called a "HABOOB," dust storms are most common between May and September in Maricopa and Pima County.
Although brief, dust storms must be taken seriously because they cause blinding conditions on the highways. Each year, an average of five people lose their lives and many more are seriously injured as a result of sudden, violent dust storms
For the second time this month, a wall of dust moved through the Phoenix area Monday evening, turning the sky brown. The dust wall, which was estimated at 3,000 feet high, reduced visibility and caused some flights out of Phoenix Sky Harbor International Airport to be delayed.
