Environment Canada has issued a special weather statement for the Barrie–Collingwood–Hillsdale area, warning that heavy rain starting tonight, March 10, 2026, could lead to local flooding. The weather service expects between 20 and 40 mm of rain to fall through Wednesday, March 11, 2026.
Forecasters say there is a risk of thunderstorms with the incoming weather system. Because the ground in the region is currently frozen or saturated from recent weather and the seasonal spring thaw, it cannot absorb much more water.
The Nottawasaga Valley Conservation Authority has also issued a flood watch for the area. Officials are warning that the rain could cause flash flooding and pooling water on local roads over the next three days.
Residents who live in low-lying areas should watch for rising water levels. Officials suggest monitoring local updates for further warnings as the rain continues through tomorrow.
