Extreme cold warning with wind chills of -30 C issued for Mississauga, Brampton, Halton and Durham

A blast of arctic air will bring harsh weather to Mississauga, Brampton, Halton, Durham and many regions of Ontario.

Environment Canada has issued an extreme cold warning for Mississauga, Brampton, Halton Hills, Milton, and northern Durham Region.

The cold Arctic air reaches southern Ontario later tonight (Feb. 2). Wind chill values are forecasted to reach -30 C tonight and Friday (Feb. 3) morning, according to Environment Canada.

After warming to around -15 C during the day Friday, wind chills may reach -30 C again Friday night into early Saturday morning.

The risks of this extreme cold are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter.

Environment Canada suggests people dress for the weather and cover up.

“Frostbite can develop within minutes on exposed skin, especially with wind chill,” Environment Canada says in the warning.

They also suggest checking on older family, friends and neighbours. And if it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.

The weather is expected to warm up a bit on Saturday to around -5 C in the day, and Sunday’s temperature could hit a balmy 4 C.

⚠️ Extreme Cold Warnings expanded to include most of the province ⚠️
