Frigid Arctic winds blowing down through the mountains and prairies are causing temperatures to plummet tonight and driving wind chills down to the point where exposed skin can freeze in as little as five minutes.
With chilly temperatures spreading across western Canada due to an Arctic airmass moving down from the north, wind chills are already down to -30 or below this evening, and have even reached down below -40 in Saskatoon. Through the night and into Friday morning, most regions of southeastern Alberta and southern Saskatchewan are supposed to reach wind chills of -40 or possibly below. The mountain valleys of eastern British Columbia are expected to see wind chills of at least -35, with down to -40 for the B.C. Peace River and Yellowhead regions.

However, with the winds, there is even a greater risk and exposed skin can freeze in as little as five minutes. ItRead More »from Extreme wind chills prompt warnings in B.C., Alberta and Saskatchewan
