Environment Canada issued a rainfall warning for Stouffville, Ontario, on March 11, 2026, as heavy rain is expected to cause flooding on local roads. The weather service warns that the ground is currently frozen or soaked, which means it cannot absorb the incoming water.
Forecasters expect between 20 and 40 mm of rain throughout the day. Some areas could see even higher amounts if thunderstorms develop during the storm.
Water is likely to pool in low-lying areas and on streets across the community. Residents are advised to stay away from rivers, creeks, and culverts where the rain could cause the ground to wash away.
Drivers should not travel through flooded roadways. The warning remains in place for the Newmarket, Georgina, and Northern York Region areas as the weather system moves through.
