You don’t have to be a local to know our summer monsoon can create towering walls of dust that roll up and into the Valley. They are an obvious hazard to drivers, but now a new study, decades in the making, confirms these filthy monsters are hazardous to your health.

Meteorologist Sean McLaughlin is joined by Dr. James Crooks to discuss the study and the danger to your health.
