Environment Canada has issued a heavy rain warning for the Ottawa-Gatineau region this weekend, with forecasters tracking a system that could bring significant rainfall across the National Capital Region on Saturday and into Sunday.
What to Expect
The warning covers Ottawa and surrounding areas, with heavy rain expected to arrive Saturday and persist through the weekend. Forecasters are monitoring the potential for:
- Significant rainfall accumulation — potentially enough to cause localized flooding in low-lying areas
- Ponding on roads and standing water in intersections
- Reduced visibility during the heaviest bands of rain
- Swollen waterways — the Rideau River and smaller tributaries could see elevated levels
Residents in flood-prone areas — including parts of Constance Bay, Cumberland, and Manotick — should monitor conditions closely.
Travel and Safety
If you're heading out this Saturday:
- Allow extra travel time — wet roads dramatically increase stopping distances
- Watch for flooded underpasses and avoid driving through standing water; even shallow water can stall vehicles
- Cyclists and pedestrians: wear high-visibility gear and be cautious near puddles and drainage grates
- Check OC Transpo alerts in case of service disruptions on low-lying routes
Home Preparation Tips
- Clear your eavestroughs and downspouts before Saturday if possible
- Check your sump pump is functioning
- Move valuables from basements in flood-risk zones
- Know your nearest emergency shelter location if you live in a flood-prone area
City Resources
The City of Ottawa has sandbags available at several locations for residents in at-risk flood zones. Call 311 for distribution site details.
Residents can also monitor road conditions at ottawa.ca and Environment Canada's latest alerts at weather.gc.ca.
Looking Ahead
After the weekend rain system clears, forecasters expect a gradual return to more seasonal conditions next week. But for Saturday at least, pack an umbrella and keep non-essential outdoor plans flexible.
Stay safe Ottawa — it's going to be a wet one.
