Cecilia Wessels snapped the picture of her husband, Theunis, on Friday evening as the twister passed near their home in Three Hills, Alberta, Canada.
She said cutting the grass was on her husband's to-do list, and as he started the task, she went for a nap.
Wessels said she was woken by her nine-year-old daughter who was upset that there was something like a tornado in the sky, but her father wouldn't come inside.
Theunis Wessels said the tornado was actually much further away than it appears in the photo, and that it was moving away from them.
