Cornwall, Ontario, is expecting unseasonably warm temperatures this weekend that could lead to slushy roads and localized flooding. The combination of warming and rain is expected to melt snow quickly, creating difficult conditions for drivers and pedestrians on March 7 and March 8, 2026.
According to Environment Canada, the temperature is forecast to reach 10°C on Saturday and 8°C on Sunday. These temperatures are significantly higher than the typical early March high of 0°C.
The rapid snowmelt and forecasted showers can overwhelm city drainage systems. This often leads to water pooling on sidewalks and the development of potholes on local streets as the frozen ground begins to thaw.
Residents are encouraged to clear snow, ice, and debris from storm drains near their homes to help water flow into the sewer system. This simple action can help prevent water from backing up into streets or pooling near house foundations.
Following safety advice from Hydro One, homeowners should also ensure their downspouts are pointing away from their houses. Taking these steps helps manage the runoff as the community transitions through this spring-like weather cycle.
