Heat Warning in effect for:

  • City of Toronto

Humidex values reaching 43 are expected.

The extreme heat event will continue through Thursday. This will be the most significant heat event in the past few years.

Temperatures on Wednesday and Thursday are once again forecast to climb into the low to mid thirties. Humidex values will also increase, reaching values near forty on both days.

Overnight low temperatures are expected to be in the low twenties, except high teens in some rural areas, providing little or no relief from the heat.

A cool down is expected by Friday with the passage of a cold front.

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.

Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.

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.
