Avalanche Summary

A small storm slab was triggered by a skier on an east aspect in the alpine in the Howson Range yesterday.

Otherwise, avalanche activity over the past week has been limited to small wet loose avalanches and cornice falls during periods of warm, sunny weather.

Snowpack Summary

In the alpine, up to 20cm of new snow has fallen on a melt-freeze crust on sunny slopes, or over cold snow on shady slopes.

In most areas at treeline you will find only a trace of new snow over a crust.

This new snow may have been redistributed by northwest and southwest winds, building wind slabs on lee slopes in isolated areas.

The middle of the snowpack is strong and contains numerous hard crusts. Near the ground, weak faceted crystals exist. There hasn't been avalanche activity on this layer recently, but it remains on our radar as it may become active with abrupt changes to the snowpack, such as rapid loading (heavy snowfall or rain) or prolonged warming.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
