What is the official blizzard weather meaning?
Environment and Climate Change Canada defines a blizzard as a winter storm with sustained or frequent gusts of 40 km/h or higher, combined with falling or blowing snow that reduces visibility to less than 400 metres for at least three consecutive hours. Temperature alone is not a criterion — blizzards can occur when the air is relatively mild, as long as wind and snow meet the thresholds. The live forecast above will show whether your area is under a blizzard warning.
What happens during a blizzard and how should you prepare?
During a blizzard, near-zero visibility can cause whiteout conditions, making driving impossible and walking disorienting. Wind chill can drop temperatures dangerously low within minutes. Power outages are common as ice and wind bring down lines. Before a blizzard hits, stock a 72-hour emergency kit, charge devices, and secure outdoor items. If you must go out, dress in layers and tell someone your route — but the safest action is to stay indoors until the warning ends.
How is a blizzard different from a snowstorm?
A snowstorm brings heavy snow but not necessarily high winds. A blizzard requires sustained winds of 40 km/h or more and visibility below 400 metres for three hours, regardless of snowfall rate. Many blizzards involve blowing snow rather than fresh snow.
When was the last blizzard in Canada?
Major blizzards hit parts of the Prairies in early 2024 and Atlantic Canada in February 2024. Environment Canada issues warnings each winter; check the live forecast above for current blizzard weather today in your region.
Can a blizzard happen without snow falling?
Yes. A “ground blizzard” occurs when strong winds lift already-fallen snow, creating whiteout conditions with no new precipitation. These can happen hours after a snowstorm ends and are common in open areas like the Prairies.
