Environment Canada has issued heat warnings across a vast region spanning from southeastern Saskatchewan to western Quebec, depicted on maps with fiery hues of yellow and orange. This week, four provinces are experiencing scorching temperatures, feeling like the mid-40s Celsius due to high humidity.
Southern and central parts of Manitoba, along with nearly all of Ontario including major cities like Toronto and Ottawa, are under heat warnings. The weather agency cautions about elevated humidity levels, posing risks of heat exhaustion and poor air quality in certain areas.
Yellow alerts indicate potentially hazardous weather conditions that “may cause” disruptions or health impacts, while orange alerts signify a higher likelihood of these effects. The orange warnings extend from just south of Regina through Winnipeg to the Quebec border, where temperatures in the 30s are anticipated, reaching a peak of 38 degrees Celsius in Thunder Bay, Ontario.
In Saskatchewan, Manitoba, and northwestern Ontario, the heat is expected to peak today, with records already broken in Manitoba as seven communities set new temperature records on Sunday. Portage la Prairie surpassed a temperature record dating back to the Second World War, hitting 35.7 degrees Celsius.
The combination of hot and humid air could worsen air quality, especially with recent wildfire smoke adding to the pollution levels. Cities like Toronto and Winnipeg are providing access to water, cooling stations, pools, and other facilities to help residents cope with the extreme heat.
To stay safe during this heatwave, Environment Canada advises watching for signs of heat exhaustion such as headaches, dizziness, and fatigue. It’s crucial to check on older adults, individuals living alone, and other vulnerable groups multiple times a day. Additionally, staying hydrated, seeking cooler environments, scheduling outdoor activities in the cooler parts of the day, and following public health guidelines are recommended measures to beat the heat.
As temperatures soar, it’s essential for residents to take precautions and prioritize their well-being by following expert advice and utilizing available resources to stay cool and healthy.
