Environment Canada is calling for extreme cold and dangerous wind chills in northern Alberta on Tuesday night.
Cold arctic air has invaded much of the province and is expected to bring temperatures of –30C to –35C overnight.
With winds near 15 to 20 kilometres an hour, the air will feel as cold as –40C to a bone rattling –50C, Environment Canada forecasts.
The federal weather agency warns anybody going outdoors to monitor weather conditions. With those wind chill values, exposed skin may experience frostbite in less than 10 minutes.
