A spectacular dust storm that swept through Western Australia's Pilbara region is causing a social media sensation.
The red storm descended near the coastal town of Onslow at around 5.30pm (WST) on Monday and reportedly forced flights due to land in the area to divert to the Learmonth airbase at nearby Exmouth.
The storm was clearly visible to people in the air, and by workers at Chevron's massive Wheatstone gas project, who captured images and submitted them to the popular Perth Weather Live website.
The Facebook posts were immediately shared hundreds of times.
The Bureau of Meteorology says the dust phenomenon is caused by the wind flow from a storm front agitating sand and dust as it moves.
The dust storm is the second to hit the area in recent weeks, with similar pictures captured of a storm that struck the Pilbara coast ahead of the arrival of Tropical Cyclone Narelle.
