What Is a Blowing Snow Advisory?

A blowing snow advisory is an official alert used when wind is expected to lift loose snow from the ground (or combine with falling snow) and reduce visibility, creating hazardous travel conditions. Blowing snow can develop quickly and may affect open roads, highways and rural areas more severely.

While an advisory is generally lower severity than a warning, conditions can still become dangerous—especially when visibility drops and roads drift over rapidly.

Typical Blowing Snow Advisory Conditions

  • Gusty winds causing drifting snow and reduced visibility
  • Visibility reductions that can change rapidly by location
  • Hazardous driving conditions on exposed roads and highways
  • Increased risk of sudden whiteout patches in open areas

Exact thresholds and advisory criteria vary by region and are determined by Environment and Climate Change Canada.

Blowing Snow Advisory vs Other Winter Alerts

  • Blowing Snow Advisory: Reduced visibility and hazardous travel due to windblown snow.
  • Blizzard Warning: Severe and sustained near-zero visibility with strong winds and blowing snow.
  • Snow Squall Warning: Brief, intense snowfall causing sudden near-whiteout conditions.
  • Snowfall Warning: Heavy snow accumulation expected over a short period.
  • Winter Storm Warning: Multiple severe winter hazards occurring together (snow, wind, ice).

Common Impacts of Blowing Snow

  • Travel hazards: sudden visibility loss, drifting snow, slick roads and reduced stopping distances.
  • Rapidly changing conditions: clear stretches of road can shift to near-whiteout within minutes.
  • Service disruption: delays, minor closures and slower emergency response in rural areas.
