Extreme cold warnings extend from north-west Alberta into Ontario as Environment Canada put out the alerts on Tuesday afternoon including for Lloydminster, Wainwright, Vermilion, Provost also, Bonnyville, St. Paul, Cold Lake, Lac La Biche and as well, Unity, Maidstone, St. Walburg and the Battlefords.
For this region, the federal meteorological service writes extreme wind chill values in the -40 to -45 range are expected tonight for most of southern Saskatchewan as a bitterly cold Arctic air-mass settles over the region. Also, the wind chill may moderate during the day, but extreme cold will continue through the week.
Temperatures are expected to return to near seasonal values this weekend.
Environment Canada advises to watch for cold related symptoms like shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes.
Protect yourself by covering up appropriately as frostbite can develop within minutes on exposed skin, especially with wind chill.
Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frostbite and hypothermia.
