    Northeast wind is forming slabs across many aspects and elevations. Expect the most reactive slabs in immediate lee terrain, such as just below ridgetops.

Confidence

Moderate

  • Uncertainty is due to how quickly the snowpack will recover and gain strength.

Avalanche Summary

Extensive snow transport was observed during Monday’s outflow winds. While no avalanches were reported, this event and ongoing winds are likely forming triggerable slabs across many elevations and aspects.

Snowpack Summary

Strong, shifting winds have heavily affected alpine and treeline terrain, building wind slabs on many aspects and in some places extending into the trees.

More than 100 cm of heavy snow fell last week, which has strengthened the snowpack and reduced the chance of triggering older layers from early December (which include buried surface hoar and crusts).

Snowpack depths exceed 350 cm at treeline.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind-affected terrain.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
