A low-pressure area threatening sometimes violent thunderstorms is heading south-western Quebec on Thursday, with the possibility of afternoon tornadoes in high humidity.
Environment Canada has issued a special weather report for the Outaouais, Montreal, Laurentides, Lanaudière and part of the Montérégie sectors.
“The main threats associated with these storms are strong gusts of wind as well as torrential rain,” said the federal agency, which is not ruling out the possibility of tornadoes later in the day.
Skies will be overcast almost everywhere in those areas, where mercury will rise with a Humidex 38 in Montreal and Montérégie, while showers are expected in Abitibi and areas to the north, the federal agency forecasts.
The weather will be generally cloudy in the center of the province, with still seasonal temperatures and a risk of thunderstorms for the Quebec, Saguenay and Mauricie regions.
In the east of the province, the Bas-Saint-Laurent and Gaspésie regions will experience some sunny spells with alternating sun and clouds, while patchy showers are expected after midday on the north coast.
