Hot and humid conditions will continue today and into early this week.
Mostly sunny skies will allow daytime temperatures to reach the low thirties, with humidex values approaching forty. These unseasonably warm temperatures and high humidex values will persist into early this week.
A cold front is expected to move across Southern Ontario through the day Wednesday bringing cooler temperatures for the remainder of the week.
Extreme heat affects everyone.
The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
Reduce your heat risk. Schedule outdoor activities during the coolest parts of the day.
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.
Outdoor workers should take regularly scheduled breaks in a cool place.
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.
