yellow warning - rainfall - in effect

Effective: Wed November 4, 2026, 3:58 PM
Expires: Thu November 5, 2026, 7:58 AM

Significant rainfall continues. What: Additional rainfall amounts of 25 to 50 mm. Multi-day rainfall totals near 80 mm, with higher amounts possible. When: Continuing tonight and ending Thursday morning. Discussion: Some areas have received in excess of 50 mm from Monday through this afternoon.

For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources office. Visit https://www.ontario.ca/page/floods for the latest details. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on social media using #ONStorm.

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.
