There may be some relief from the heat in Toronto this weekend.
According to Environment Canada’s heat warning on Tuesday, the prolonged period of hot weather will continue through the rest of this week. But, the agency adds that “a slightly cooler airmass may move into the area this weekend, however there is considerable uncertainty.”
On Tuesday, daytime high temperatures in excess of 30°C, with humidex values in the high 30°Cs to low 40°Cs, are expected this week.
Overnight lows near 20°C are also expected through this period, providing little relief from the heat.
By the weekend, when the relief is set to arrive, Toronto is expecting two days of rain, with a high of 27°C on both Saturday and Sunday.
For now, the hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.
So never leave people or pets inside a parked vehicle.
Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heatstroke, and the worsening of some health conditions.
Toronto has created a map of the city’s Emergency Cooling Centres for residents to cool down during the extreme heat.
Be sure to drink lots of water, as officials suggest, if you plan to spend time outside.
