13. "These dust storms (happen) every summer...for as long as people here have been keen keeping track."

Yes, but in recent years they have become more severe and happen nearly yearly and multiple times per year. This is caused by the arid conditions in the mid and upper mid west. Drought conditions there leave so much more topsoil exposed to wind erosion giving the 'haboobs' the increasing intensity areas west of the Continental Divide.

In other words, the return of the Dust Bowl.
