Freezing rain is currently affecting Ottawa, with temperatures hovering near 0 °C. The live forecast above shows ice accumulation of 2–5 mm through mid-morning, followed by a transition to plain rain as temperatures rise above freezing by early afternoon.
How long will freezing rain last in Ottawa?
Based on the live forecast above, freezing rain should taper off by early afternoon as a warm front pushes temperatures above 0 °C. The most hazardous period is the morning commute, when untreated surfaces will be slickest. Conditions improve steadily after that, though lingering wet roads may refreeze if skies clear overnight and temperatures drop again.
What hazards does freezing rain create?
Ice accumulation as little as 2 mm can make sidewalks and roads treacherous. Thicker ice (5 mm or more) may bring down tree branches and power lines, leading to local outages. Driveways and stairs become especially dangerous; sand or salt is recommended. For current warnings, check the weather warning page.
What exactly is freezing rain?
Freezing rain occurs when snow melts into rain as it falls through a warm layer, then refreezes on contact with cold surfaces. It creates a clear glaze of ice that is highly slippery.
How is freezing rain different from sleet?
Sleet is frozen rain that bounces off surfaces, while freezing rain coats everything in ice. Sleet is less dangerous for power lines but still hazardous for driving.
When should I avoid driving in freezing rain?
Avoid driving if ice is actively falling or if roads are visibly glazed. If you must go out, reduce speed, brake gently, and keep extra distance. Check the Ottawa weather page for updates.
