Another weather alert has been tacked onto the Montreal metropolitan region.
Along with the city’s heat warning, Environment Canada has added a severe thunderstorm watch alert for Montreal.
Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce large hail, damaging winds, and/or torrential rainfall.
The weather agency says this afternoon and evening, conditions for the development of severe thunderstorms are “favourable.” Environment Canada says to “keep in mind that severe thunderstorms can produce tornadoes.”

The alert warns that large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees, and overturn large vehicles. “Lightning kills and injures Canadians every year,” says the alert. “Remember, when thunder roars, go indoors!”
Simultaneously, Montreal’s heat warning — initially issued on Monday — has entered its fourth consecutive day.
Environment Canada says a “warm and humid air mass will affect the province of Quebec” and will persist until Saturday.
“The days will be hot,” says the weather agency. “It will remain warm and uncomfortable at night with lows near 20ºC until Saturday morning.”
Heat warnings are issued when very high temperatures or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
The weather agency says high heat risks are greater for young children, pregnant women, older adults, people with chronic illnesses, and people working or exercising outdoors.
Citizens are urged to drink plenty of water, stay in a cool place, and limit outdoor activity. The agency reminds locals to never leave people or pets inside parked vehicles.
Both alerts are in effect, at the same time, for the following areas:
- Châteauguay – La Prairie area
- Laval area
- Longueuil – Varennes area
- Montréal Island area
Environment Canada urges citizens to continually monitor the weather once an alert has been issued.
