See a sandstorm#1 of 5 things to do in Sydney
The most powerful sandstorm in Sydney and throughout Australia, took place in 2009 and brought with it more than five million tons of sand. Red dust paralyzed traffic on the roads, all flights were canceled. A suffocating cloud of dust hung over the city for more than a day, and the visibility was limited to a few meters. It is not always possible to predict the occurrence of dust storms.
The essence of a sandstorm is a dislocation of a huge amount of sand and dust from the ground by the wind. Raised in the air, the dust soon settles around a considerable area and shades everything in the predominant color of the soil of the region. Sandstorms and other similar phenomena occur in the hottest time of the year. The extremely hot temperatures in Australia have become the cause of forest fires and fire tornados.
