Wild and weird clouds spotted on the Coorong | PHOTOS/VIDEO

Keen Naracoorte fisherman Cam McCully estimates that he has made more than 300 trips to the Coorong, but on the weekend, he found something more than fish in the ocean.

"What happened is that initially I was night fishing," Cam explained.

"I had my rods in my rod holders, and at 4am I woke up because it was really windy. I wasn't sure where it was coming from, and it only lasted for about two minutes, so I went back to sleep.

"That's when I woke at 6am on Sunday, and I found that both of my rods had been knocked to the ground. 

"Then at about 6.45am there was a beautiful sunrise, so I started to take some photos. 

"Then I saw this cloud on the horizon, and it was racing in towards me. The sunlight made it pink after it had been blinding white, it was quite amazing."

Cam estimates that the original cloud passed only 30 metres above his head, and it was so low in the sky that he could have hit it with a tennis ball and racquet. 

A few more clouds followed the original cloud, but while these clouds were smaller - Cam estimates around 200m or 300m - the first cloud was so immense that Cam couldn't see the the ends of it. 

With the clouds came winds, however there were clear skies in their wake. Cam estimates that similar clouds must have passed over his campground earlier that Sunday morning, causing the small wind storm in the early hours.

What Cam saw was later confirmed as a 'roll cloud' or volutus cloud, a rare type of cloud belonging to the arcus family. Roll clouds regularly occur along coast lines due to cold fronts clashing with warmer temperatures, and are analysed via mesoscale meteorology. 

They are more common in northern Australia, which makes Cam's sighting even more of a curious event. 

"I've never seen anything like it in my life," he said.

"I spoke with Adam Stewart, who used to run the Salt Creek Roadhouse, and he's lived up there all of his life. He said that he had never seen anything like that either."

As Cam was the only camper for a couple of kilometres around, if he hadn't recorded it via photos and video, the beautiful yet bizarre roll cloud simply would have disappeared, well - into thin air.
