yellow watch - severe thunderstorm - in effect

Effective: Thu June 18, 2026, 9:40 AM
Expires: Fri June 19, 2026, 1:40 AM

Conditions this afternoon and evening will be favourable for the formation of severe thunderstorms capable of producing strong wind gusts, large hail and heavy rain. A slight risk of a tornado is also associated with these thunderstorms. Nautical activities may be hazardous due to sudden, severe wind gusts over bodies of water. ### Local utility outages are possible. Damage to roofs, fences, branches or soft shelters is possible. Heavy rain can cause flash flooding and significant reductions to visibility. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to QCstorm@ec.gc.ca or post reports on X using #QCStorm.

When thunder roars, go indoors! Lightning kills and injures Canadians every year.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
