Environment Canada is warning residents in large swaths of Yukon of bitter wind chill reaching as low as minus-50-degrees for the next few days.
The weather agency says a stationary arctic ridge of high pressure over the region will bring wind chill values below minus-40 from Carmacks north to Dawson and the Alaskan border.
The cold temperature is also forecasted for much of the Dempster Highway to Inuvik in the Northwest Territories as well as the area near Old Crow to the north.
The warning says the conditions would allow for frostbite on bare skin to develop within minutes, and the deep freeze will not ease until Monday.
