'Mad Max'-like dust storm envelops Brazilian city in cloud of doom

A towering wave of orange dust filled the horizon and whooshed over a neighborhood in a recent video of a rare sandstorm in northwestern São Paulo, Brazil.

As the choking cloud rushed past the camera, it transformed the city skyline into a scene that would have looked right at home in the arid wasteland of the post-apocalyptic "Mad Max" movies.

On Sunday (Sept. 26), residents of several cities in the state of São Paulo experienced the unusual storm. Footage of the event was captured in four Brazilian municipalities on multiple cameras belonging to Clima au Vivo (CV), a private company that uses live camera feeds to monitor and record weather for local news agencies, according to the company website.

In an edited video, uploaded to YouTube that day, dense clouds of dust extend up into the sky and envelop parts of Barretos, Morro Agudo, Bebedouro and Viradouro. Residents of the cities Ribeirão Preto, Araçatuba, Jales, Franca and Presidente Prudente in the state of São Paulo also witnessed the terrifying power of the light-swallowing sandstorm, according to Agência Brasil, the national public news agency. Cities in a neighboring state, Minas Gerais, were enveloped by dust as well, agency officials said in a statement.

"The day turned into night," Nacho López Amorín, a meteorologist with the Argentinian news channel Canal de la Ciudad, wrote Sept. 27 in a tweet sharing footage of the lofty dust cloud.

A storm like this, in which strong winds whip up a vast wall of dust that can measure thousands of feet high, is known as a haboob. The term, which originated in Sudan, comes from the Arabic word "habb," which means "to blow," and these fast-moving dust walls, which typically appear in the aftermath of thunderstorms, are common in arid parts of the world, according to the American Meteorological Society (AMS).

Haboobs are rare in this part of Brazil, but recent high temperatures and dry conditions in the region fueled strong winds that whipped up a blinding storm cloud, gusting at 57 mph (92 km/h) in Ribeirão Preto, said Andrea Ramos, a meteorologist with Brazil's National Institute of Meteorology.

"The winds helped bring the dust up from the soil, [and] the heat wave increased the temperature, as humidity rates were below 20 percent," Ramos said in the statement.

However, São Paulo residents shouldn't worry about being swallowed by another dusty haboob anytime soon, Ramos said. With the onset of cooler weather in northern Brazil and rainfall expected this month, "we won't have the conditions favoring such a phenomenon again," she said.
