The Niagara Peninsula Conservation Authority is keeping a flood outlook in place for Port Colborne, Ontario, until noon on Monday, March 9, 2026. Recent rain and warmer temperatures have left the ground soaked, which could lead to sudden water runoff and higher flows in local streams.
Officials first issued the notice on the morning of March 6, 2026, after a period of wet weather and melting. More rain is expected over the next few days, with forecasts calling for another 10 to 30 millimetres of precipitation that could include thunderstorms.
People are being told to stay away from all waterways because of fast-moving water, ice break-up, and slippery banks. The authority warns that these conditions can be dangerous for anyone walking near creeks or rivers.
Homeowners should check that their property drainage is working properly. This includes making sure that culverts, catch basins, and ditches are not blocked so that water can flow away from homes.
While widespread flooding is not expected right now, the situation can change quickly. The Niagara Peninsula Conservation Authority will continue to watch water levels and provide updates as needed.
