What to know about massive dust storms called haboobs in the Southwest U.S.

Massive walls of dust and debris called haboobs that roll through the Southwest U.S. can be awe-inspiring and terrifying, especially for motorists caught in their path. The dust storms are caused when thunderstorms produce strong downdrafts that spread out and stir up loose dust and dirt ahead of the approaching storm cell. If conditions are right, haboobs can form a wall of dust a mile or more high and many miles wide while reaching speeds of 60 mph or more.
