Environment Canada has issued a heat warning for almost all of the greater Kawarthas region for Saturday (August 6) and Sunday.
The heat warning is in effect for Peterborough County, City of Kawartha Lakes, Northumberland County, and Hastings County.
A two-day heat event is expected on the weekend, with maximum temperatures in the high twenties or low thirties. Humidex values are expected to reach the high thirties to low forties. Minimum temperatures overnight will be in the low twenties, bringing little relief from the heat.
Cooler temperatures are expected on Monday.
Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high-risk category. The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
Drink plenty of water even before you feel thirsty and stay in a cool place. Check on older family, friends. and neighbours and make sure they are cool and drinking water. Never leave people or pets inside a parked vehicle. Outdoor workers should take regularly scheduled breaks in a cool place.
Environment Canada issues heat warnings when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
