Heat Warning Update – Cool Down Followed by More Heat!


The heat isn’t over yet.

Environment Canada has issued a heating warning for Sault Ste. Marie – St. Joseph Island and Searchmont – Montreal River Harbour – Batchewana Bay.

A strong cold front has ushered in a cooler and less humid air mass for today. However, the cool down will be short lived, as high heat and humidity will return for Tuesday. Daytime temperatures will again be near 30 degrees, with humidex values in the mid thirties. Low temperatures overnight will again be in the high teens to low twenties providing little relief from the heat.

As on the weekend, temperatures near the lake shores will be cooler.

Another cool down is expected by Friday with the passage of another cold front.

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.

Never leave people or pets inside a parked vehicle.


  1. I do not know how we ever survived when I was a child without knowing the HEAT INDEX. We just called everything SUMMER and enjoyed it. Weather is getting too technical and is still not very accurate.
