Low vegetation cover can especially be a problem in drought years in abandoned agricultural fields, which are generally dominated by annual plants. This means that the consequences of dust storms, including motor vehicle crashes, are high in a drought year and low in years with more precipitation. Future climate scenarios predict that drought conditions will worsen, and therefore more dust storms are likely. Photo: Dust storm near Winslow, AZ in April 2011. Seth Munson , USGS.
