Wind Chill Warnings / Cold Wave Information Supplied By Environment Canada. Wind Chill Warning In Canada, injuries from frostbite and fatalities from hypothermia are not uncommon. Wind chill can play a major role in these health hazards. Wind chill is the cooling sensation caused by the combined effect of temperature and wind. The wind chill index compares the way your skin feels like under certain wind and temperature combinations, to a temperature on a calm day. At values of -25, wind chill units begin to appear in your forecasts. When a Wind Chill Warning is issued, expect very cold temperatures combining with wind to create outdoor conditions hazardous to human activity. Wind chill warning criteria vary across the country, ranging from -55 in some arctic regions to -30 in southwestern Ontario. Warnings will be issued when the winds are expected to be at least 15 km/h and these extreme wind chills will persist for at least three hours. For wind chill values: -27 to -44 ...risk of frostbite and risk of hypothermia increases with time spent outdoors -45 or lower ...exposed flesh may freeze in minutes and there is a serious risk of hypothermia Safety Tip: There is a risk of frostbite in less than 10 minutes when the wind chill is near -40. The criteria for Wind Chill Warnings vary in different parts of the province because people do become acclimatized to winter in their area. See Map
