Toronto is preparing for a deep freeze, with Environment Canada issuing an extreme cold warning that could see wind chill values plummeting to an astonishing -30°C to -35°C. This arctic blast, gripping the Greater Toronto Area (GTA), is not just a chill in the air; it’s a serious weather event that could impact your daily life.

According to Environment Canada, 'An Arctic airmass will bring bitterly cold wind chills to the area tonight.' If temperatures or wind chills hit -30°C for an extended period, the agency emphasizes the severity of this weather, which affects various regions across southern Ontario, including Hamilton, Guelph, Windsor, London, and Barrie.

As we edge closer to mid-January, tomorrow’s high is projected to reach a bone-chilling -12°C in Toronto, marking the coldest day on record since January 2019. Expect the temperature to drop significantly by nighttime, potentially hitting -20°C, and feeling even colder when factoring in wind chill.

But that’s not all! Some areas in southern Ontario are under heavy snow warnings, with over 40 cm of snow accumulation anticipated in regions like the Bruce Peninsula, Owen Sound, Bracebridge, and Gravenhurst from lake-effect snow squalls extending into Wednesday.

Frostbite Risk: What You Must Know!

Toronto residents should brace themselves for a brisk morning on Wednesday with temperatures hitting -18°C. With additional snow set to arrive—1-3 cm expected by Thursday morning—it's crucial to be aware of frostbite risks amid such extreme cold. Frostbite can occur in less than 30 minutes if exposed skin is situated at -15°C with wind chill.

To protect yourself, dress in warm layers, cover exposed skin, and limit your time outdoors. As these cold conditions will linger until late January, it’s vital to stay informed and prepared. The bright side? As February approaches, there are signs of milder air making its way north.

Stay warm and stay safe, Toronto! The cold may be harsh, but being prepared will help you weather this chilling storm.
