Ottawa is bracing for a wet end to the weekend after Environment Canada issued a special weather statement warning that more than 50 mm of rain could fall on the city this Sunday.
What's in the forecast
According to Environment Canada, a system moving through the region is expected to bring sustained and at times heavy rainfall throughout the day Sunday, with total accumulations potentially exceeding 50 mm in the Ottawa area. That's a significant amount of rain to fall in a short window, and the agency is urging residents to stay weather-aware as the system develops.
Special weather statements like this one are issued when conditions have the potential to cause disruption, even if they don't rise to the level of a full warning. In this case, the concern is the sheer volume of rain expected to hit the capital in a single day.
Why Ottawa should pay attention
Heavy rain events like this can create real headaches for Ottawa drivers and pedestrians. Poor drainage in low-lying spots around the city — think areas near the Rideau River, parts of the ByWard Market, and older neighbourhoods with aging stormwater infrastructure — can lead to localized flooding, pooling water on roads, and reduced visibility during the heaviest bursts.
Commuters planning to be out and about this Sunday should budget extra time, watch for standing water on roads and underpasses, and avoid driving through flooded areas, since it's often hard to judge how deep the water actually is. Cyclists and pedestrians should also expect slippery conditions on multi-use pathways along the canal and river corridors.
Homeowners, especially those with basements or properties in flood-prone areas, may want to do a quick check of eavestroughs, downspouts, and sump pumps before the rain arrives to help minimize the risk of water getting where it shouldn't.
What to do before Sunday
With the heaviest rain expected to fall over a relatively short period, the City of Ottawa's stormwater system could be put to the test. Residents are encouraged to:
- Clear debris from eavestroughs and storm drains near their property
- Move any outdoor items that could be swept away or damaged by pooling water
- Check that sump pumps are working properly, if applicable
- Plan for extra travel time or consider adjusting outdoor plans for Sunday
Environment Canada notes that rainfall totals and timing can shift as the system develops, so it's worth checking for updates as the weekend approaches. As always, further weather statements or warnings could be issued if conditions change.
Stay tuned to local forecasts throughout the weekend, and if you're out on Sunday, drive with extra caution — especially on routes that have flooded before.
