Brief Description Heat Warning
Detailed Description Multi-day heat event continues. What: Daytime highs of 30 to 32 degrees Celsius, with humidex values of 37 to 40. When: Coming to an end later today. Additional information: A cooler and less humid air mass will slowly move in from the northwest today, bringing the heat event to an end. Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category. During times of high heat, your health and the health of your family and friends can deteriorate rapidly. The Ministère de la Santé et des Services sociaux du Québec, in cooperation with Environment and Climate Change Canada, recommends that you protect yourself from the effects of the heat by taking the following actions: Drink 6 to 8 glasses of water per day even before feeling thirsty. As appropriate, follow your physician's instructions regarding the amount of fluid to drink; Avoid alcoholic beverages or caffeine; If you can, spend at least 2 hours a day in an air conditioned or cool place; Take at least one cool shower or bath per day, or cool your skin several times per day with wet towels; Limit physical activities; Wear light clothes. Be sure to: Never leave a child or a baby alone in a vehicle or a poorly ventilated room, even for a few minutes; Check on and be ready to help your loved ones, especially those who are vulnerable, disabled, mentally ill or live alone. Remember that heat can also affect the health of pets. If you have any questions regarding your health, call Info-Santé by dialling 8-1-1 or ask a health care provider. In case of an emergency, call 9-1-1.
