"Dangerous thunderstorms" expected for Montreal on Tuesday: Environment Canada

Aug 11 2020, 6:00 am

Montreal is under a double-dose of weather alerts from Environment Canada.

On top of Monday’s heat warning, which remains in effect, the weather agency has also issued a Severe Thunderstorm Watch for Montreal and its surrounding areas.

“Conditions are favourable for the development of dangerous thunderstorms capable of producing very strong wind gusts, large hail, and downpour,” says the statement, calling for the atmospheric conditions to begin this afternoon and evening.

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.”

Both the heat warning and the thunderstorm watch are in effect for the following areas:

  • Châteauguay – La Prairie area
  • Laval area
  • Longueuil – Varennes area
  • Montréal Island area

Montreal’s heat warning forecasts temperatures to exceed 40ºC throughout the day, citing a “warm and humid airmass” that will settle over much of Souther Quebec this afternoon and into the evening.

Heat warnings are issued when very high temperatures and/or humid conditions are expected to “pose an elevated risk of heat illness, heat stroke, or heat exhaustion.”

Environment Canada says extreme heat affects everyone and urges citizens to drink plenty of water, wear breathable clothes, stay in a cool place, and avoid physical activity.
