The Niagara Peninsula Conservation Authority has issued a flood watch for Port Colborne, Ontario, which will remain in effect until 12:00 PM on Friday, March 13, 2026. This warning was upgraded from a previous outlook because the ground throughout the region is already soaked from melting snow and recent wet weather. When the soil is this saturated, it cannot absorb more water, which leads to a much higher risk of flooding during rainstorms.
Current weather forecasts predict that a significant amount of rain will arrive in the region starting on the evening of Tuesday, March 10, 2026. Between 35 and 55 millimetres of precipitation is expected to fall through Wednesday, which will cause water levels in local creeks and rivers to rise significantly. This alert also covers residents in southeastern Hamilton and eastern Haldimand County who may see similar conditions.
Specific areas like 20 Mile Creek near the escarpment are currently being monitored closely, as water levels there are already high and close to reaching flood elevations. Authorities are urging everyone to stay away from the edges of all waterbodies during this time. The banks of rivers and streams can become very slippery, and the high-flow water creates dangerous conditions for anyone nearby.
Residents can take simple steps to protect their homes by ensuring that drainage on their property is not blocked by leaves or trash. Checking that culverts, ditches, and catch basins are clear will help rainwater move away from the house instead of pooling in yards or basements. These small maintenance tasks are often the best way to prevent localized flooding during heavy rain events.
Local government and regional workers have also been advised to inspect the public storm systems and drainage pipes to ensure they are ready for the upcoming rain. By keeping this infrastructure clear, the community can better manage the heavy runoff expected over the next few days. Following the instructions of local emergency officials is recommended as conditions may change quickly.
