Here comes the rain, Ottawa; could this be the first sign of spring? It’s too early to tell, but the Roads and Parking Services team is ready to adjust to the unpredictable weather that March has to offer!
Forecast and conditions
Environment Canada has issued a Special Weather Statement for the Ottawa region. Periods of snow are expected to begin this morning and ice pellets this afternoon with 5 centimetres possible. Rain is expected to begin tonight with a risk of freezing rain as temperatures may be below zero as the rain begins. The temperature is then expected to quickly rise above zero and rain will continue through Wednesday with 15 to 25 millimetres possible. Given the limited ability of the frozen ground to absorb water, the rain combined with melting snow may lead to localized flooding in low-lying areas and water pooling on roads.
Changing conditions will make the transportation network messy, be prepared to adjust and take extra care when walking, driving or cycling in affected areas.
Our response
Across the City and as this system moves into the region, supervisors will keep a close eye on sidewalks, roads, and the winter cycling network, identify any areas of concern and deploy resources as needed. With the significant amount of rain on the way, we will also be monitoring areas that are prone to localized flooding and address any water pooling by ensuring catch basins and ditches are open and able to take in water.
In preparation for this rain event, crews have been proactively opening up catch basins. In the meantime, staff are asking for anyone who can to please ensure their local catch basin is clear and able to take in water. With over 100,000 catch basins in the City, they cannot do it alone and would appreciate any support you can offer.
Find your nearest catch basin using our catch basin locator map. Need to report a blocked catch basin? Let us know!
Snow removal operations will be paused
With the incoming rain and mild temperatures, snow removal operations will be paused at noon on Wednesday, March 5. Resources will be reallocated to address icy conditions on the transportation network and drainage issues. Once the system has moved out of the region, crews will be able to return to snow removal operations.
Next steps
The Roads and Parking Services team will continue to monitor this system as freezing rain warnings or freezing drizzle advisories may be required as the event draws close. Meanwhile, supervisors will continue to monitor the transportation network over the next 24 hours
