Heat warning issued for Montreal Thursday into Friday, with humidex values up to 40

Environment Canada has issued a heat warning for Montreal effective Thursday and into Friday. A hot and humid air mass is expected to bring a high of 33 degrees Celsius on Thursday, with humidex values approaching 40. Overnight, a low of 23 degrees is forecast, with a high of 26 on Friday (36 with the humidex).

The weather statement recommends taking action to protect yourself and others, determining if you or others around you are at greater risk of heat illness, and checking in on older adults, those living alone or other at-risk people multiple times a day.

“Watch for the early signs of heat exhaustion in yourself and others. Signs may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. Stop your activity and drink water. Drink water often and before you feel thirsty to replace fluids. Close blinds or shades and open windows if outside is cooler than inside. Turn on air conditioning, use a fan or move to a cooler area of your living space. If your living space is hot, move to a cool public space such as a cooling centre, community centre, library or shaded park.”
