Dust storms can create a wall of dust that miles wide and thousands of feet high. When one hits, visibility can drop down to a quarter of a mile or less.
When that happens, the local branch of the National Weather Service will send out a weather emergency alert. Odds are you've received one on your phone. Sirens, however, are not part of the messaging equation.
