A heat warning has been issued for the Quinte region.
Environment Canada says a hot and increasingly humid air mass will last through to at least Sunday. Slightly cooler and less humid conditions may arrive on Monday.
Daytime high temperatures: 31 to 34 degrees Celsius.
Overnight low temperatures: 20 to 24 degrees Celsius.
Humidex values: high 30s Saturday increasing to low 40s Sunday.
Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.
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.
Outdoor workers should take regularly scheduled breaks in a cool place.
Heat warnings are issued when very high temperatures or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
