Environment Canada has issued a heat warning for the weekend for much of the greater Kawarthas region, including southern Peterborough County, southern Kawartha Lakes, and all of Northumberland.
Hot and humid conditions expected to continue Saturday (August 21) and Sunday and then possibly into early next week.
Maximum temperatures are expected to reach 31°C, with humidex values ranging from 36°C to 40°C. There will be little relief overnight, with a low of 21°C.
On Sunday, afternoon temperatures Sunday may be a degree or so lower than on Saturday. However, temperatures may once again rise to the low 30s early next week.
Hot and humid air can also bring deteriorating air quality and can cause the Air Quality Health Index to approach 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.
Seek a cool place such as a tree-shaded area, swimming pool, shower or bath, or air-conditioned spot like a public building.
Never leave people or pets inside a parked vehicle.
