Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Sugarbowl, Clemina, North Monashee.

New snow will not be enough to cover early-season hazards.

Monitor areas of wind-deposited snow as they will be deeper and more reactive areas may be reactive.

Confidence

Moderate

Avalanche Summary

No new or recent avalanches have been reported in our region.

Consider supporting your backcountry community by submitting your own observation in a MIN report.

Snowpack Summary

New snow will be transported by southwest winds at higher elevations. In general, the snowpack is mostly unconsolidated. In areas unaffected by the wind large surface hoar crystals can be found.

At treeline, the height of snow is between 50 to 90 cm and decreases significantly as you drop in elevation.

Read the new Forecaster's Blog for more on the early-season snowpack.

Weather Summary

Sunday

Cloudy, 6 to 13 cm accumulation by the end of the day, alpine wind south 25 km/h gusting to 65, treeline temperature -3 °C.

Monday

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Expect shallow snow cover that barely covers ground roughness.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
