Environment Canada is predicting that the extreme weather in the east of the country brought on by the polar vortex should begin to ease on Friday.
However, the agency is still predicting that the cold arctic air combined with westerly winds will result in wind chill values on Thursday night to as low as minus 45.
“Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter,” warns the agency.
“Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill, and remember, if it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.”
The extreme weather has resulted in eight deaths in the U.S. since the beginning of the cold snap.
