In sintesi

Continue to assess wind slabs on steep, exposed terrain, particularly in shallower areas where buried crusts may create favorable sliding surfaces.

    Variable winds have created wind slabs at upper-elevations.

    If triggered, wind slabs could step down to multiple buried crusts, creating larger than expected avalanches, particularly in areas with a shallower snowpack.

Confidence

Moderate

  • Confidence is due to a stable weather pattern with little change expected.
  • Uncertainty is due to the complexity of the snowpack’s structure.

Avalanche Summary

A few small (size 1 to 2) rider triggered avalanches where reported over the weekend. These were primarily around treeline elevations on southerly terrain, failing 10 to 40 cm deep.

Snowpack Summary

Variable winds have created wind-affected surfaces at upper elevations, overlying generally low-density recent storm snow.

The mid-snowpack contains a melt-freeze crust buried in mid-December that exists at treeline elevations and below.

A second crust, buried in November, sits near the base of the snowpack and is associated with faceted snow. This layer extends into alpine terrain and has been a lingering concern throughout the season, particularly in shallow alpine areas where the mid-December crust is absent. In these locations, the November crust may lack a supportive overlying layer and remain susceptible to triggering.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid lee and cross-loaded slopes at alpine and treeline elevations.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
