Weather watches and warnings for severe thunderstorms and tornadoes have been issued across Ontario and Quebec, raising concerns about significant weather conditions.
The alert began with a thunderstorm warning for southwestern and central Quebec around 5 a.m. EDT Thursday. It has since expanded to cover areas from the northern Ontario region of Manitouwadge-Hornepayne, near Lake Superior, to Wellington County, Ont., east to Hawkesbury, Ont., near Montreal, and up to north of Mistissini, Que. These regions are now under a mix of severe thunderstorm and tornado watches.
Environment Canada’s notice warns of favorable conditions for the development of dangerous thunderstorms capable of producing very strong wind gusts, damaging hail, and heavy rain this afternoon and evening. Residents are urged to seek local severe weather advisories for more detailed information.
Potential Impacts and Safety Measures
The affected areas could experience hot and humid temperatures, feeling like up to 33°C, with potential wind gusts of up to 110 km/h, hail up to three centimeters in diameter (nickel to toonie size), and possible tornadoes. Major cities like Toronto, Ottawa, Montreal, and Quebec City currently remain outside the alert boundaries, but there is a risk that severe storms could extend into these areas.
The federal alert advises against water-related activities due to the risk of sudden, violent wind gusts and lightning strikes. Residents in affected areas are advised to move to the lowest floor of their homes, away from external walls and windows. Temporary shelters like tents, mobile homes, or vehicles should be avoided in favor of sturdier structures. If no immediate shelter is available, lying in a low spot and protecting the head from flying debris is recommended.
Current Situation and Outlook
The most urgent alert is in the Manitouwadge-Hornepayne region, Ont., where a severe weather warning is in effect. Environment Canada notes that severe thunderstorms and tornadoes can develop rapidly, sometimes with less than 30 minutes’ notice.
Storms are expected to be intermittent as they move through the Great Lakes region, potentially affecting Toronto and Montreal later in the day with lesser risks. The storms may reach Atlantic Canada by Friday.
