Massive walls of dust and debris, known as haboobs, frequently roll through the U.S. Southwest, posing a terrifying spectacle for motorists.

The article explains how haboobs form from strong thunderstorm downdrafts stirring up dust and dirt from arid areas, and provides safety advice for those caught in these storms, emphasizing the dangers of reduced visibility.
