Heat Warning

Issued at 22:45 Thursday 09 July 2020

A prolonged period of hot weather continues.

Daytime high temperatures in excess of 30 degrees Celsius, with humidex values in the high thirties to low forties, are expected this week. Overnight lows near 20 degrees Celsius are also expected through this period, providing little relief from the heat.

A slightly cooler airmass may move into the area this weekend, however there is considerable uncertainty and the conditions may persist for a few areas into Saturday.

Please refer to your public forecast for further details on expected temperatures.

Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.

Never leave people or pets inside a parked vehicle.

###

Extreme heat affects everyone.

The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.

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

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@canada.ca or tweet reports using #ONStorm.
