In addition to the Extreme Cold Warning that was issued on Thursday morning, Environment Canada is now showing that the city’s temperature will drop to -21°C this evening.
And that’s without the wind chill.
The warning, issued early today, will be in effect until further notice.
According to the City of Toronto, Extreme Cold Weather Alerts are issued when the temperature is forecast to reach -15°C or colder, or when the wind chill is forecast to reach -20°C or colder.
Environment Canada warns that “bitterly cold wind chills near -30 are expected overnight and into Friday morning.”
“Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frostbite and hypothermia,” the warning says.
The city is reminding the public that extreme weather poses a serious threat to vulnerable residents, those who work outdoors, people with a pre-existing heart condition or respiratory illness, elderly people, infants, and young people.
Everyone should take precautions. A warming centre is open at Metro Hall by 7 pm the day an alert is called, and remains open continuously until noon on the day an alert is terminated.
The city is also asking that residents help vulnerable people by calling 311 if there is a need for street outreach assistance, or to call 911 if the situation is an emergency.
On the other side of the frigid night, temperatures are expected to soar up to -8°C Friday morning.
Which, compared to what’s projected for tonight, sounds almost tropical.
