Environment Canada has issued a rainfall warning for Ottawa, with 30 to 50 millimetres of rain expected to begin tonight and continue through Thursday. The warning comes as the region braces for significant precipitation that could lead to localized flooding in low-lying areas.
Timing and Impact
The rain is forecast to start this evening and persist into Thursday, with the heaviest rainfall expected overnight. Total accumulations of 30 to 50 mm are likely, which may cause water pooling on roads and flash flooding in some areas. Residents are urged to clear drainage ditches and ensure sump pumps are working.
Safety Precautions
Environment Canada advises drivers to avoid driving through flooded roads, as water depth can be deceptive. Pedestrians should also exercise caution near streams and culverts. The agency will continue to monitor the situation and update warnings as necessary.
This rainfall event follows a period of mild weather in the region. The Rideau Canal, a popular recreational waterway, is expected to see water levels rise. City crews are on standby to respond to any flooding reports.
For the latest updates, residents can check Environment Canada's website or local news outlets. The warning is expected to remain in effect until Thursday evening.
