Niagara Falls freezing amid polar vortex

Extremely cold temperatures over the weekend in the northern United States and Canada have left Niagara Falls looking a bit iced up, while Lake Erie and Lake Ontario are also reportedly struggling with the weather.

This video, filmed yesterday, shows the waterfalls covered in snow an ice as slush runs with the current.

The filmer later wrote online: "The weekend's extreme cold has dramatically surged the ice cover over the Great Lakes.

"This video was shot in the afternoon of 15 Feb 2016 showing the ice-cover and frozen mist over Niagara Falls."
