Environment Canada has issued a heat warning for the region through the long weekend.

It was issued on Friday, and is expected to last until a cold front moves in on Tuesday.

The heat warning is in effect for:

  • Guelph – Erin – Southern Wellington County
  • Kitchener – Cambridge – Region of Waterloo
  • Mount Forest – Arthur – Northern  Wellington County

Humidexes above 40 C are expected.

Overnight temperatures are only expected to fall between 20 C and 24 C, providing minimal relief from the heat.

Environment Canada reminds people to never leave people or pets inside a parked vehicle.

Heat-related health risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
