Environment Canada has issued a heat warning for Sarnia-Lambton, with hot and humid conditions expected Monday and into Tuesday.
The national weather agency is forecasting temperatures to reach 31 C combined with overnight lows near 21 C.
A humidex value reaching into the low forties is also anticipated on Tuesday. The hot and humid conditions will likely come to an end Tuesday 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.
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.
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.
