12:16 AM EDT Wednesday 17 July 2024 Heat Warning in effect for: Rawdon - Joliette area Humidex values will remain near 35 on Wednesday. The warm and humid air mass currently affecting Southern Quebec will exit the area overnight Wednesday night. 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. Drink plenty of water regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration. If you are in an overheated area, seek a cool place such as a tree-shaded area, splash pad, misting station, or air-conditioned spot like a public building. Watch for early signs of heat illness (feeling unwell, fatigue, thirst, headache) as these can rapidly evolve into life-threatening emergencies. Move to a cooler environment immediately, such as a shaded or air-conditioned space. Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to QCstorm@ec.gc.ca or tweet reports using #QCStorm .
