Residents in Milton, Ontario, should prepare for heavy rain and potential flash flooding starting the night of Tuesday, March 10, 2026. Environment Canada has issued a special weather statement predicting 20 to 40 mm of rain to fall through Wednesday, March 11, 2026.
The total amount of rain could be even higher in areas that experience thunderstorms. This weather is being caused by a series of storm systems that will move through the region over a 24-hour period.
Local experts are concerned because the ground is currently frozen or soaked from previous weather, which means it cannot absorb the heavy rainfall. This situation creates a high risk for flash floods, water pooling on roads, and drainage issues in low-lying areas.
Conservation Halton is monitoring the risk and is asking residents and children to keep a safe distance away from all watercourses. This includes staying clear of structures like bridges, culverts, and dams where water levels may rise quickly.
