Regions

Crowsnest North, Crowsnest South.

With little snow, deeper snowpack areas offer the easiest travel but are also where wind slabs may linger.

Assess steep slopes for dense or stiff snow before committing.

Confidence

Moderate

Avalanche Summary

No new avalanches reported.

Snowpack Summary

Total snowpack depths are roughly 60 to 80 cm, tapering quickly at lower elevations.

The upper snowpack is variable, with wind-affected surface snow in open terrain and softer snow in sheltered areas. This overlies a crust that formed in early November. The lower snowpack consists of multiple crusts, and in some areas a layer of weak, sugary facets can be found near the ground.

In many areas, especially below treeline, there is not enough snow to smooth out surface roughness or reach the threshold needed for avalanches.

Weather Summary

Sunday Night

Mostly clear skies. 20 to 30 km/h west ridgetop wind. Treeline temperature -15 °C.

Monday

Mostly cloudy. 40 to 50 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Tuesday

Cloudy. Flurries, 3 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -9 °C.

Wednesday

Partly cloudy, isolated flurries, 1 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Watch for areas of hard wind slab on alpine features.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

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.
