Hot and humid conditions will continue today. Daytime highs will again be in the low 30s, with humidex values reaching around 40. The exception will be locales near the shorelines of the Great Lakes, where temperatures will be a few degrees cooler. A few thunderstorms are possible this afternoon and early evening ahead of an approaching cold front.

The cold front will pass through Southern Ontario this evening bringing an end to this heat episode. Monday will be noticeably cooler and less humid.

While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for – older adults – infants and young children – people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses – people who work in the heat – people who exercise in the heat – people without access to air conditioning and – homeless people.

Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.

Never leave people or pets in your care inside a parked vehicle or in direct sunlight.
