A massive dust storm has swept through parts of the US state of Arizona. The thick wall of dark dust in Pinal County was carried by thunderstorm winds - a phenomenon known as a haboob, according to the National Weather Service. The term 'haboob' comes from Arabic and refers to a 'strong wind' or 'gale'. In the United States, these events are most common in the southwest.

The dust storm not only affected visibility but also raised concerns regarding air quality and public safety. Local authorities urged residents to stay indoors and avoid outdoor activities during the storm. This incident illustrates how climate change may be contributing to the increased frequency and severity of such extreme weather events.
