Avalanche Summary

No new avalanches have been observed but visibility has been limited during the storm.

Snowpack Summary

5 - 10 cm of new snow since Friday, with up to another 20 cm expected by Monday. New snow and wind has formed windslabs in alpine and treeline lees. This overlies the January drought layer which includes facetted snow on northerly aspects or a melt freeze crust below treeline and on steep solar slopes into the alpine. Generally, the snowpack has become weak and facetted.

Snowpack depths at treeline range from 50 - 120 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
