‘Dangerously hot and humid’ weather to hit southern Ontario
Regions across southern Ontario are under a heat warning as “dangerously hot and humid” weather conditions are expected for most of the week, Environment Canada said.
“A prolonged heat event will begin today,” Environment Canada said in a special weather alert posted just before 6 a.m. Monday.
The multi-day heat event is expected to last until Thursday or Friday, the weather agency said. The warning extends from Windsor across the Greater Toronto Area to Ottawa and north to Moosonee.
Environment Canada said daytime highs are expected to hit between 30 C and 35 C with humidex values of 40 to 45.
There will be “little relief” through the overnight as lows are expected to be 20 C to 23 C with humidex values of 26 to 30.
However, the weather agency said temperatures and humidex values could be several degrees cooler near the Great Lakes.
