Kernpunkte

Even small avalanches can have serious consequences in extreme cold.

Carefully assess or avoid steep, wind-loaded slopes.

    Wind slabs may be slow to bond as cold temperatures continue to facet the snowpack.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Observations are limited due to extreme cold. On Monday, a size 2 wind slab occurred on a south aspect near Tutshi Lake, indicating that ongoing outflow winds are continuing to build wind slabs.

Snowpack Summary

The upper snowpack is heavily wind affected, with widespread sastrugi and hard wind slabs in open terrain. Cold temperatures are faceting the snowpack, allowing wind slabs to persist longer than usual.

Surface facets are forming and will probably bond poorly to the snow arriving this weekend.

Snowpack depths vary widely due to wind, but average around 100 cm across the region.

Terrain and Travel Advice

  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Watch for areas of hard wind slab on alpine features.
