HEAT WARNING
A prolonged heat event will begin on Monday. Dangerously hot and humid conditions are expected through most of the week and perhaps into the weekend. Daytime highs on Monday through the week are expected to be near 35 degrees Celsius with humidex values of 40 to 45. There will be little relief through the overnight as lows are expected to be 20 to 24 degrees Celsius with humidex values of 28 to 35. Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category. Extreme heat can affect everyone's health. The health risks are greater for older adults, infants and young children, pregnant people, people with physical and/or mental illnesses, and people with disabilities or mobility issues. Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions. Heat stroke is a medical emergency! Call 911 or your local emergency number immediately if you or someone you are caring for has a high body temperature and are confused, has stopped sweating or becomes unconscious. While waiting for help, cool the person right away: move them to a cool place, apply cold water to large areas of the skin and fan the person as much as possible. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or tweet reports using #ONStorm.
