Amid the frigid temperatures brought on by the polar vortex, parts of Niagara Falls came to a standstill this week as the waters literally froze in place as they fell.

A few dramatic photos of the frozen falls were posted to social media. This one shows the American side of the falls frozen over on Wednesday, when the temperature dropped to a low of – 19 C with the wind chill.

Normally at this time of year, the temperature in Niagara Falls reaches a low of – 8 C, according to Environment Canada.

The temperature in Niagara Falls is forecast to rise for the remainder of the week, with a high of 10 C on Saturday, according to the weather agency.
