Canada’s national weather agency is warning of a "prolonged heat event" starting Monday that is expected to bring “dangerously hot and humid conditions” to much of southwestern Ontario.
Late Sunday afternoon, Environment and Climate Change Canada (ECCC) issued a heat warning for a large swath of Southern Ontario, including London, Toronto, Niagara, Owen Sound, and Kingston, Ont.
According to Environment Canada, daytime highs in the area are expected to soar into the mid-thirties, with humidex values of 40 to 45 degrees Celsius, through much of the week.
“There will be little relief overnight as lows are expected to be 20 to 23 C with humidex values of 26 to 30," the warning reads.
In Toronto, thunderstorms are also in the forecast for Sunday night into Monday.
Environment Canada issues a heat warning when two or more consecutive days are forecasted with daytime maximum temperatures of 31 degrees Celsius or higher, along with a minimum nighttime temperature of 20 degrees Celsius or higher, or when two or more consecutive days are forecasted with humidex values reaching 40 or higher.
“Due to climate change, Toronto is expected to experience higher summer temperatures, unpredictable weather and more extremely hot days,” the city said.
