HEAT WARNING
A prolonged heat event continues through Friday or Saturday. Dangerously hot and humid conditions are expected.Daytime highs are expected to be 30 to 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 23 degrees Celsius with humidex values of 26 to 30. Temperatures and humidex values may be several degrees cooler near the shores of the Great Lakes.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. Never leave people, particularly children, or pets inside a parked vehicle.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 is 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.

SPECIAL AIR QUALITY STATEMENT
High levels of air pollution are possible late this afternoon and evening. Hot and sunny conditions are expected to cause increasing ground-level ozone concentrations north of Lake Ontario. Moderate risk AQHI values are expected throughout the day with the potential of short-term high risk AQHI values late in the afternoon and in the evening.Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.People with lung diseases, such as asthma and COPD, can be particularly sensitive to air pollution. They will generally experience more serious health effects at lower levels. Pollution can aggravate their diseases, leading to increased medication use, doctor and emergency room visits, and hospital visits.Exposure to air pollution is particularly a concern for children, the elderly, and those who have underlying medical conditions such as lung or heart disease.Be air aware! Check your local weather forecasts and alerts so you know when to take extra care.Visit airhealth.ca for information on how to reduce your health risk and your personal contribution to pollution levels, as well as for current and forecast AQHI values.Please continue to monitor alerts and forecasts issued by Environment Canada.Issued by Environment Canada and the Province of Ontario
