Another stunning dust storm swept through Onslow yesterday, causing a flight to be diverted and coating the town in Pindan sand.

Winds of nearly 70km/h whipped up an imposing wall of orange that hit Onslow about 5.30pm.

A Skywest flight from Perth to Onslow had to change course because of the dust.

The flight left Perth at 2.30pm and was forced to divert to Learmonth Airport, eventually returning to Onslow just before 8pm.

Steve Hardy, who lives on Front Beach, said residents knew how to prepare for the dust storms.

“You know they’re coming - you can see them from miles away, so you make sure everything’s taped up,” he said.

“After the one in January, we had three inches of dirt on our front porch.”

Although yesterday’s dust storm was not as spectacular as last month’s, Mr Hardy said it was still impressive.

“You get that lovely Pindan red,” he said.

“It sounds like rain on the roof. It does hurt if you’re outside – it’s like being in a sand blaster.”

Bureau of Meteorology officer Peter Clegg said the wall of dust was caused by wind gusts from a storm front.

“You get an outflow of wind gusts coming out the front of the storm itself,” he said.

“If there’s enough dry dust, winds of 67km/h will definitely kick some of it up.

“It’s the orange dust that you get up there that gives you that great contrast with white clouds.”

He said the stormy weather was expected to continue in Onslow all week.
