Heat Wave Peaks Across Ontario, Quebec, Vermont with Health Warnings

A widespread heat wave is impacting large parts of North America with extremely high temperatures and health risks. In California's NorthState, temperatures are expected to peak near 108 degrees, with little overnight relief, prompting advisories to avoid prolonged sun exposure and stay hydrated. Ontario and Quebec are also experiencing a multi-day heat wave with highs near 35 C and humidex values close to 40 C, leading to multiple heat warnings and recommendations to limit outdoor activities during peak heat. Hamilton, Ontario, has seen its sixth heat warning of the summer, with temperatures above 30 C and humidex values between 35 and 40, alongside guidance on preventing heat stroke and using cooling centers. Similarly, Vermont and the Champlain Valley are facing days of near 100-degree heat, with local authorities opening cooling centers and providing public access to shaded and air-conditioned spaces to mitigate heat risks. Across these regions, officials emphasize the importance of heat safety measures, including hydration, staying indoors during peak heat, and utilizing cooling centers to reduce the risk of heat-related illnesses.
