Heat warning in place for the Kawarthas for the weekend

Humidex values of 40°C or higher arrive on Friday, with nighttime temperatures in the twenties

Heat warning

Environment Canada has issued a heat warning for all of southern Ontario, including the Kawarthas.

Significant heat and humidity will arrive on Friday (July 19), with daytime temperatures in the low-to-mid thirties and afternoon humidex values of 40°C or higher.

There will be little relief in the evenings, with nighttime minimum temperatures in the low-to-mid twenties expected for Friday and Saturday (July 20).

A cooler and less humid air mass is forecast to arrive by Monday in the wake of a weak cold front on Sunday (July 21).

Environment Canada issues heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.

While extreme heat affects everyone, the risks are greater for young children, pregnant women, older adults, people with chronic illnesses, and people working or exercising outdoors.

Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

Never leave people or pets inside a parked vehicle, and outdoor workers should take regularly scheduled breaks in a cool place.
