Environment Canada issued a major heat warning on Sunday morning for the greater Montreal area, Montérégie, Lanaudière and the southern Laurentians.
“Hot and humid weather will continue through Sunday evening with daytime Humidex readings between 34 and 39. The nights will remain uncomfortable with temperatures around 20 degrees Celsius,” reads the warning from the federal agency.
“Drink plenty of water, even before you feel thirsty, and stay cool. Reduce your heat risks. Organize your outdoor activities during the cooler hours of the day,” they suggested.
On Saturday, a thunderstorm developed in the eastern Lanaudière region. Strong gusts associated with this storm caused damage to the electrical network in the municipalities of Saint-Cuthbert and Saint-Barthélemy. As of Sunday morning, more than 4,600 subscribers in the Laurentians and Lanaudière are without power.
These storm cells could continue Sunday from the end of the morning. All the sectors around the St. Lawrence River are the most at risk. However, the heat and humidity should end early in the week.
