Scorching temperatures prompt heat warning for Region of Waterloo and Guelph
Highs in the low to mid 30s forecast for Friday with humidex values of 40
Environment Canada has issued a heat warning for the Region of Waterloo, as well as Guelph and Erin.
Daytime temperatures are forecast in the low to mid 30s with humidex values of 40 on Friday.
Nighttime temperatures won't provide much relief from the heat either, with forecast lows in the mid-twenties on Friday and Saturday, Environment Canada said.
The Region of Waterloo, Kitchener, Cambridge, Guelph, Erin, Southern Wellington County, Mount Forest, Arthur and Northern Wellington County were all included in the warning.
Environment Canada said young children, pregnant women, older adults and people with chronic illnesses or those working outdoors were at greater risk of becoming ill from the extreme heat.
They're reminding people to never leave other people or their pets in a parked car.
Cooler and less humid air is expected to arrive on Sunday.
