Advisory Lifted for Ottawa
Ottawa got a brief but hazardous weather scare this week as Environment Canada issued, and then lifted, a freezing drizzle advisory for the region. The advisory flagged dangerous icy conditions that had the potential to make roads, sidewalks, parking lots, and other outdoor surfaces slippery and treacherous for residents moving around the city.
Freezing drizzle occurs when supercooled water droplets freeze on contact with cold surfaces, forming a thin but deceptively dangerous glaze of ice. Unlike heavier freezing rain, it can be harder to spot, making it particularly risky for drivers and pedestrians who may not realize conditions have deteriorated until they're already in a difficult situation.
What This Means for Commuters
For Ottawa commuters and pedestrians, the lifting of the advisory is welcome news. Freezing drizzle events, even brief ones, can cause significant disruptions to the city's bus network, cycling infrastructure, and foot traffic, especially on hills, bridges, and intersections that are slower to be treated by road crews.
OC Transpo riders may have noticed delays or cautious driving during the advisory period, which is standard protocol when icy road surfaces are a factor. Cyclists navigating the city's multi-use pathways should remain cautious even after an advisory lifts, as shaded or lower-traffic surfaces can stay icy well after the main roads have been treated.
Staying Safe During Late-Winter Weather
March in Ottawa is notoriously fickle. The city sits in that tricky seasonal window where above-freezing afternoons can quickly give way to below-zero nights, creating repeated freeze-thaw cycles that keep sidewalks and roads in a constant state of flux.
Environment Canada recommends the following during freezing drizzle or icy conditions:
- Slow down and increase following distance when driving
- Wear footwear with good traction when walking on potentially icy surfaces
- Watch for black ice, especially on bridges, overpasses, and shaded areas
- Keep an eye on weather alerts via the Environment Canada website or the WeatherCAN app
The City of Ottawa's road crews work around the clock during winter weather events, prioritizing arterial roads, bus routes, and school zones before moving to residential streets and pathways.
Keep Watching the Forecast
While the advisory has been lifted, Ottawa's weather can shift quickly this time of year. Residents are encouraged to stay tuned to Environment Canada forecasts, particularly during overnight and early morning hours when temperatures are most likely to dip below freezing and create fresh icy patches.
Spring may be on the horizon, but Ottawa's winter isn't done with us just yet, so keep those ice scrapers handy for a little while longer.
