Toronto-based company IceGen Inc. have explained how they produce snow for the Winter Olympic Games in Sochi despite a surge in temperatures at the Games.

IceGen business developer David Bowden says they have three truck trailers in Sochi creating about 30,000 cubic feet of snow a day.

The machines can produce snow even when temperatures float around the 20 C mark.

Bowden told CTV: "I would call it spring snow. It's not fluffy December snow coming out of the sky, it's the kind of heavy packing snow that you find in the spring.

"But it's a lot nicer than cross-country skiing in mud.

"We did a lot of experimentation in Norway and Finland. We had athletes ski on it in August and September and said they said it's great snow, it's very skiable."

There hasn't been a single day of below freezing temperatures since the Games began.
