“Extremely hot and humid conditions” are expected in Toronto on Wednesday, with humidex readings making it feel like it’s almost 43 C outside, Environment Canada says.
The forecast calls for daytime high temperatures of 31 to 33 C and humidity values of 42 to 43, the federal weather agency said.
A special weather forecast is currently in effect in the city.
Wednesday’s overnight lows, forecast to be 21 to 23C, will provide some relief from the heat, he added.
No heat advisory will be issued for Toronto
The Federal Weather Agency says it will not issue a heat warning because daytime high temperatures are not expected to reach the warning threshold Thursday due to the passage of a cold front.
Heat warnings call for hot and humid conditions to last two days, with daytime temperatures of 31C or humidex readings of 40, and nighttime lows of 20C or higher between those two days, it said.
Air quality may deteriorate due to hot and humid air and the Air Quality Health Index may approach the high risk category, it said.
Beating the heat
To keep calm in the heat, the Met Office advises the following:
- Drink plenty of water before you feel thirsty and stay in a cool place.
- Check on older family, friends and neighbors to make sure they are cool and drinking water.
- Never leave people or pets in a parked vehicle.
- Keep homes cool and block out the sun by closing curtains and blinds.
- Outdoor workers should take regularly scheduled breaks in a cool place.
