In a tweet, Urgence Québec, the public agency responsible for charting possible emergency situations, has alerted the public to the potential development of severe thunderstorms across much of the southwestern portion of the province.
There is also an accompanying threat of tornado activity.
Environment Canada, meanwhile, has several severe thunderstorm watches in effect across southern Quebec, including Montreal. "Do not forget that severe thunderstorms can produce tornadoes," the federal agency states under the alert for Montreal on its website.
"Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall," Environment Canada continues.

A heat warning is also in effect for the city of Gatineau, which has already seen tornado activity this year. In early June, a tornado ripped through the Ottawa-Gatineau area, damaging property. No one was injured.
In the map below from Environment Canada, yellow indicates the regions under a severe thunderstorm watch while the spot of red at the bottom left represents the heat warning for Gatineau.
Residents in other areas, both north and south of Montreal, should prepare for wind that may reach speeds of as much as 90 km/h and 40 to 50 milimeters of rainfall.
Urgence Québec encourages residents in affected areas to contact Environment Canada by email at meteoQC@canada.ca to report any damage as a result of severe weather.
"Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!" Environment Canada adds.
Stay tuned for updates on this developing situation.
