The City of Toronto, Canada has issued an Extreme Cold Weather Alert on Monday, December 12, 2017, that will be in effect until further notice. The warning was issued based on information from Environment Canada, Dr. Eileen de Villa, Toronto's Medical Officer of Health. Extreme Cold Weather Alerts are issued when the temperature is forecast to reach -15 °C (5 °F) or colder, or when the wind chill is forecast to reach -20 °C (-4 °F) or colder.
Although temperatures Toronto, the fourth largest city in North America (population 2.8 million) are expected to plunge to -10 °C (14 °F) overnight Tuesday, the real feel will be closer to -20 °C (-4 °F). The temperatures are expected to feel like below -10 °C at least until Friday, December 15, when they will slightly rise.
"Exposure to cold weather can be harmful to your health," the City of Toronto health officials warn. "Hypothermia occurs when the body's core temperature drops below 35 °C (95 °F) and can have severe consequences, including organ failure and death. Frostbite can also occur in cold weather when skin freezes and in severe cases can lead to amputation when deeper tissues freeze."
Those most at risk of cold-related illness are people experiencing homelessness or those under-housed, those who work outdoors, people with a pre-existing heart condition or respiratory illness, elderly people, infants and young children. People with heart problems can experience worsening of their condition up to several days after cold weather occurs.
Extreme Cold Weather Alerts activate local services that focus on getting and keeping vulnerable residents inside. These services include additional shelter beds, notification to community agencies to relax any service restrictions, availability of transit tokens in some drop-ins, and overnight street outreach.
Between November 15, 2017 and April 15, 2018, winter respite services are available continuously at several drop-in locations across the city, operating 24 hours a day/7 days a week. Call 311 for locations or check the web app at toronto.ca/homelesshelp.
The City asks that residents help vulnerable people by calling 311 if there is a need for street outreach assistance. Call 911 if the situation is an emergency.
During an Extreme Cold Weather Alert, members of the public are encouraged to take the following precautions:
• Check the weather report before going outside.
• Dress in layers, making sure your outer layer is windproof, and cover exposed skin.
• Wear a hat, warm mittens or gloves, and warm boots.
• Stay dry. Your risk of hypothermia is much greater if you are wet.
• Choose wool or synthetic fabrics for your clothes instead of cotton, because cotton stops keeping you warm once it gets wet.
• Seek shelter if you normally spend long periods outside. Depending on the wind chill, exposed skin can freeze in minutes.
• Drink warm fluids, other than alcohol.
• Warm up by taking regular breaks in heated buildings when enjoying winter activities outside.
• Consider rescheduling outdoor activities, or limiting time outdoors, during colder temperatures, especially if it's windy.
• Heat your home to at least 21 degrees Celsius if infants or elderly people are present.
• Call or visit vulnerable friends, neighbors and family to ensure they are not experiencing any difficulties related to the weather.
