Durham Region Health Department has issued an ‘Extreme Cold Weather’ alert that will be in effect for the evening of Monday, January 10 through to the evening of Tuesday, January 11.
Environment Canada said the region is likely to see a period of very cold wind chills, with temperatures between minus 21 and minus 28 degrees Celsius. Wind chill values will be near minus 30.
It said bitterly cold Arctic air combined with light winds will bring extremely cold wind chills to the region beginning near midnight last night. This is the coldest air so far this season. Wind chills will improve Tuesday morning after sunrise.
Extreme cold puts everyone at risk. Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter, said Environment Canada asking residents to dress warmly in layers that you can remove if you get too warm. The outer layer should be wind resistant. Cover up as frostbite can develop within minutes on exposed skin, especially with wind chill.
It also said further local accumulations of as high as 10 cm of snow was possible by midnight.
Extreme Cold Weather Alerts are issued by Durham Region Health Department when Environment Canada forecasts a temperature of -15°C or colder, and/or a wind chill of -20°C or colder.
