Environment Canada has issued a special weather statement for Hanover, Ontario, warning of heavy rain that could lead to flash floods and pooling on local roads. The statement, issued on March 10, 2026, forecasts between 20 to 40 mm of rain for the town and Southern Grey County through Wednesday.
Government weather experts warn that the ground is currently frozen or soaked from previous weather, which means it cannot absorb the rain effectively. This situation increases the chance of sudden flooding, especially in low-lying areas, and might include a risk of freezing rain as the showers move through the region.
The Saugeen Valley Conservation Authority has also put a flood watch in place for the local area. This watch is set to last until 4:30 p.m. on Wednesday, March 11, 2026, as water levels are expected to rise in local streams and rivers.
Officials say some areas could see even higher amounts of rain if thunderstorms develop. Residents are encouraged to check the drainage around their homes and be careful when driving due to potentially hazardous conditions and water sitting on the roads.
