Environment Canada has issued a special weather statement for the Region of Waterloo, Ontario, as heavy rain on March 10, 2026, and March 11, 2026, brings an increased risk of flash flooding. The region is expected to see significant rainfall that could lead to water pooling on local roads and in low-lying areas.
Weather experts from Environment Canada predict between 20 and 40 mm of rain will fall through Wednesday. Some areas could see even higher amounts if thunderstorms move through the community during this time.
The ground across the region is currently frozen or already soaked from previous weather, which means it will have a hard time absorbing the new rainfall. This creates a higher risk for sudden flooding and dangerous driving conditions where water collects on the pavement.
The Grand River Conservation Authority has already issued flood watches and warnings for the entire local watershed. These warnings come after a period of warm weather and melting snow that had already caused river levels to rise in the area.
Local residents are advised to stay away from riverbanks and low-lying spots where water may gather quickly. Drivers should take extra care on the roads and avoid driving through deep pools of water while the rain continues.
