Points saillants

Reactive wind slabs linger in exposed terrain. While unlikely, small avalanches in motion could step down to much deeper weak layers.

    Westerly winds have formed reactive wind slabs in exposed terrain at and above treeline.

    A crust with facets deep in the snowpack remains a concern. While the probability of triggering this layer is low, the consequences could be severe.

Confidence

Moderate

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

Avalanche Summary

A recent, small wind slab avalanche was observed in very steep, extreme northeast-facing alpine terrain.

Otherwise, no new avalanches have been reported, but observations are extremely limited in the region.

Snowpack Summary

In exposed alpine and treeline areas, wind-affected surfaces persist. On south-facing slopes at higher elevations, a thin sun crust is likely to form overnight.

Approximately 40 to 80 cm of recent snow continues to settle above a melt-freeze crust that is thin or absent in alpine terrain, while thicker and widespread at treeline and below.

Near the bottom of the snowpack, a significant crust exists with associated faceted snow.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.
