A photograph of a man mowing a lawn with a tornado swirling behind him has caused a storm on social media.

Cecilia Wessels took the picture of her husband Theunis on Friday as the twister passed near their home in Alberta, Canada.

She says cutting the grass was on her husband's to-do list and as he started the task, she went for a nap.

But she was woken by daughter who was upset that there was something like a tornado in the sky, but her father would not come inside.

Mr Wessels said the tornado was actually much further away than it appeared in the photo and was moving away from them.

He said he was keeping an eye on it all the time.

No one was injured.
