- The remarkable footage shows the cloud rolling across the ground like a wave
- It formation is thought to be a ‘stratus cloud’ which stick close to the earth
- Gobsmacked onlookers filmed the amazing scene in Leavitt, Canada last month
This is the awe-inspiring moment a ‘tsunami cloud’ sweeps across the landscape rolling over the earth like a gigantic wave.
The clip, shot in Leavitt, Alberta, Canada, shows the eerie weather formation gathering in a scene chillingly reminiscent of ice cloud brought by the white walkers in Game of Thrones.
Engulfing the whole horizon, the rare cloud creeps across the frame until it blankets the entire view in a whiteout.
Lasting several minutes, the unusual cloud formation brought with it several inches of snow in the hours following, marking a very cold beginning to Canada’s spring.

Shayna Olsen watched on speechless as she filmed the remarkable event on March 30 this year.
‘It looked like something from the Day After Tomorrow,’ College student Shayna said.
‘It was a huge wall of clouds that just engulfed everything.
‘The clouds rolled in as quickly as they left – they completely covered the sky and it started to snow.
The unusual formations are believed to be a rare type of Stratus clouds.
Stratus clouds form when a sheet of warm, moist air lifts off the ground and depressurizes.
This then forms a pocked of low pressure close to the ground which allows the cloud to hang near the earth’s surface – creating the spooky tsunami effect.

As the cloud consumes the landscape, visibility becomes worse until it is a total whiteout
Shawna said she felt ‘lucky’ to have been able to witness such an incredible event as she had never seen anything like it before.
‘I’ve seen cold front move over the mountains before, but never this close to the ground,’ she added.
‘It was incredibly interesting and I was amazed at the clouds and their speed.
‘It was very much a case of being in the right place at the right time – I feel lucky to have witnessed it.’
