Environment Canada has issued a heat warning for the entire Kawarthas region beginning Tuesday (July 4).
The heat warning is in effect for Peterborough County, Kawarthas Lakes, Northumberland County, Hastings Highlands, and southern Haliburton County.
A two- or three-day hot and humid event is expected to begin on Tuesday and last into Wednesday or possibly Thursday for eastern regions.
Maximum temperatures will be the high twenties to low thirties, with humidex values in the high thirties to low forties. Minimum temperatures overnight, in the high teens to low twenties, will bring little relief.
These hot and humid conditions will begin to end from west to east Wednesday night.
Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.
Extreme heat affects everyone. Drink plenty of water even before you feel thirsty and stay in a cool place.
