Regions

Crowsnest North, Crowsnest South, Elkford East, Elkford West.

Remain cautious in wind-affected terrain at upper elevations.

Wind slabs have been reactive in the region.

Confidence

Moderate

  • Uncertainty is due to limitations in the field data.

Avalanche Summary

On Saturday, a large wind slab—possibly triggered by a cornice fall—was reported near Gladstone Mountain in the southern part of the region.

On Friday, explosive control triggered a size 2 wind slab out of a lee crossloaded slope in the alpine.

Looking forward, wind slabs may remain reactive to human triggering on Sunday.

Snowpack Summary

Strong winds have developed wind slabs in lee and cross-loaded features at upper elevations. In parts of the region, a weak surface hoar layer may be buried around 40 cm down.

The mid-snowpack is well consolidated, with a thick melt-freeze crust present at treeline and below, but generally absent in the alpine.

Near the bottom of the snowpack, a crust with facets is considered unlikely to trigger, except with large loads or in thin snowpack areas.

Weather Summary

Saturday Night
Partly cloudy. 40 km/h west ridgetop wind. Treeline temperature -3 °C with a possible temperature inversion. Freezing level around 1500 m.

Sunday
Mostly cloudy. 40 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level rising to 1700 m.

Monday
Mostly cloudy. 0 to 5 mm of precipitation as snow or rain at treeline. 50 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level around 2000 m.

Tuesday
Mostly cloudy. 0 to 2 mm of rain at treeline. 40 km/h west ridgetop wind. Treeline temperature 3 °C. Freezing level rising to 2700 m.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Watch for areas of hard wind slab on alpine features.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.

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.
