A heat event starts today bringing temperatures that will feel like almost 40 C in southern Ontario.

A heat warning was issued as daytime temperature highs are expected to be near 31 C with humidex values of 35 to 39 C today (July 8), Environment and Climate Change Canada says.

There will be little relief through the overnight as lows are expected to be 20 C or above, the warning continues.

A cooler airmass is expected to arrive Tuesday night but the temperatures will still hit a high of 31 C.

There is also a 30 per cent chance of showers in the afternoon with a risk of a thunderstorm on Tuesday.

Environment and Climate Change Canada warns there are health risks or older adults, infants and young children, pregnant people, people with physical and/or mental illnesses, and people with disabilities or mobility issues during these heat events.

Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

Drink plenty of water regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration, the warning states.

Never leave people, particularly children, or pets inside a parked vehicle.
