Montreal can tack on the potential for severe thunderstorms to its heat warning for Monday.
A double-dose of weather alerts are in effect for Montreal as Environment Canada has issued a severe thunderstorm watch for the city and its surrounding areas.
“Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain,” states the alert.

Boaters are being warned that “strong wind gusts” may surprise them over bodies of water.
The weather agency says that strong wind gusts can toss loose objects, damage weak buildings, break branches off trees, and overturn large vehicles. Heavy downpours can also cause flash floods and water pooling on roads.
“Lightning kills and injures Canadians every year,” the alert said. “Remember, when thunder roars, go indoors.”
The alert, issued just after 10 am on Monday morning, is in effect for the following areas:
- Châteauguay – La Prairie area
- Laval area
- Longueuil – Varennes area
- Montréal Island area
In terms of the heat alert, temperatures are expected to reach “feels like” highs of 41ºC by this evening. Heat warnings are issued when very high temperature or humid conditions are expected to pose an “elevated risk of heat illnesses, such as heat stroke or heat exhaustion.”
The weather agency reminds people to never leave children alone inside a poorly ventilated vehicle and urges neighbours to check in on vulnerable citizens.
Environment Canada asks locals to continually monitor weather updates once an alert has been issued.
