Residents of Port Colborne should remain cautious of potential localized flooding as the region deals with saturated ground conditions following significant rainfall. While the heavy rainfall warning previously issued by Environment Canada has ended, the Niagara Peninsula Conservation Authority (NPCA) has a Watershed Conditions Statement – Flood Outlook in effect until 9:00 AM Tuesday, April 7, 2026.
Recent weather has brought heavy moisture to the area, with 15 to 50 millimetres of rain falling over the past four days. The conservation authority notes that while major or widespread flooding is not expected and creeks and rivers remain below critical levels, the ground is currently too saturated to absorb much more water. This increases the risk of minor, localized flooding in low-lying and flood-prone areas.
For the remainder of Sunday, April 5, the forecast calls for mainly cloudy skies with a 60 percent chance of showers and west winds at 30 kilometres per hour gusting to 50 kilometres per hour, with a high of 8 C. As the evening progresses, these conditions are expected to clear slightly, with a 40 percent chance of showers early in the night and winds eventually becoming light by midnight. Temperatures are forecast to drop to a low of 1 C.
Drivers should be aware that water may pool on local roads, particularly in low-lying areas, and visibility could drop suddenly during heavier periods of rain. Residents with questions regarding local watershed conditions can reach out to the flood risk management officer, Ryan Kitchen, at 905-788-3135 ext. 269 or by email at [email protected].
