The agency further forecasts that chill values might even fall below minus 40 in those communities, while it urges people to pack carefully in case it is absolutely necessary for them to head outside despite the dangerously cold conditions.
However, despite the warning issued to all surrounding areas, Calgary has been left out from the warning due to urban island effect. Friday December 6th is still anticipated to be a very cold day in Calgary, as chances are it still might be recorded as the coldest day of 2013 in the city. The temperature had already dropped below -30 C on early Friday morning, which when couple with wind chill made it feel like -42.
