Special weather statement in effect for:

  • Elliot Lake - Ranger Lake

First heat event of the season expected today.

High temperatures today are forecast to reach low to mid 30 degrees Celsius in many areas. Tonight, minimum temperatures in the upper teens will provide little relief from the heat.

Cooler air is expected to arrive Wednesday.

These conditions pose a health risk when you are not used to the heat.

Everyone is at risk from heat, especially older adults; infants and young children; and people with chronic illnesses.

You are advised to 1) drink plenty of cool liquids before feeling thirsty; and 2) keep cool by dressing for the weather and spending more time in a cool place.

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

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