Dust storms such as this near Orroroo still occur on the Black Rock and Walloway Plains south and north of Orroroo respectively.

Wind erosion is commonly associated with light sandy soils. However, loamy soils are also susceptible to wind erosion under certain conditions. Overgrazing or overcropping can lead to the breakdown of soil structure making these soils vulnerable to strong winds because of the lack of soil cover, leading to dust storms rather than sand drift.
