Environment Canada issues multi-day heat warning for Toronto

Aug 22 2020, 2:14 pm

This hot weekend might just roll into a hot start of the week as Environment Canada has issued heat warnings for Sunday and Monday in Toronto.

According to the agency, a very warm air mass is expected to impact the Golden Horseshoe region of southern Ontario over the next two days.

“This event is expected to be mainly confined to urban areas where minimum temperatures will be highest,” Environment Canada said in their warning.

On Sunday, things are expected to heat up quite a bit. There’s a forecasted high of 32ºC, though the humidex will make this feel like 40ºC. The UV index will also be “very high,” so if you are spending time outdoors be sure to wear sunscreen.

There is also a 30% chance of showers in the afternoon with risk of thunderstorms continuing into the evening, and a low of 21ºC.

The heat event is expected to dissipate on Monday night when a cooler air mass moves into the region. The day will remain hot though as Monday is calling for a mix of sun and cloud with a 60% chance of showers and a high 30ºC.

The night will bring cloudy periods with a 40% chance of showers and a low of 19ºC.

According to Environment Canada, hot and humid air can also bring deteriorating air quality and cause the Air Quality Health Index to approach the high risk category, placing young children, pregnant women, older adults, people with chronic illnesses, and people working or exercising outdoors at a greater risk than others.

Everyone is advised to watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heatstroke, and the worsening of some health conditions. Remain in a cool place and drink water if you feel thirsty.

The agency also says never to leave people or pets inside a parked vehicle.
