Toronto Cold Weather: −35°C Wind Chill Continues

Toronto residents are bracing for dangerously cold temperatures tonight, with wind chill values expected to plummet to -35 C, prompting an official warning from Environment Canada.

The national weather agency’s alert covers Toronto and much of the Greater Toronto Area, raising concerns about frostbite and cold-related illnesses.

• A yellow cold warning is in effect for Toronto and surrounding areas.
• Wind chill values could reach -35 C overnight and again Sunday night into Monday.
• Frostbite can develop within minutes on exposed skin in these conditions.
• Vulnerable populations are at increased risk.

What’s the biggest risk with this cold snap? The extreme cold poses a threat to everyone, but particularly to young children, older adults, individuals with underlying health conditions, and those without adequate shelter. Frostbite can develop on exposed skin in a matter of minutes when wind chill is factored in.

Forecast Details for Toronto and the GTA

Today, February 9, 2024, will be mainly sunny with northwest winds at 30 km/h, gusting to 50 km/h. While the high is forecast to reach -13 C, the wind chill will make it feel closer to -22 C this afternoon, increasing the risk of frostbite.

Tonight, a few clouds are expected, with northwest winds at 20 km/h becoming light later in the evening. The overnight low is predicted to be -22 C, with wind chill values near -30 C. Similar dangerous conditions are anticipated Sunday night into Monday.

Who is Most at Risk?

Environment Canada emphasizes that extreme cold is a hazard for all, but certain groups are more vulnerable. This includes young children, older adults, people with chronic illnesses, those experiencing homelessness, and anyone who spends significant time outdoors, whether for work or recreation.

Cold-related symptoms can manifest as shortness of breath, chest pain, muscle pain and weakness, numbness, and changes in skin colour, particularly in the fingers and toes. Prompt action is crucial if these symptoms appear.

Outdoor workers are advised to take frequent breaks in warm shelters. Anyone experiencing symptoms of frostbite should immediately seek indoor warmth and begin the rewarming process.

Residents are encouraged to stay informed about weather alerts and forecasts as conditions may change. Monitoring updates from Environment Canada is recommended.
