Kernpunkte

New snow incrementally loads a weak layer. We have uncertainty about where this layer is triggerable and when the tipping point will be. The best defense is conservative terrain choices.

    New snow and wind form wind slabs in leeward terrain features at upper elevations.

    Größe

    New snow continues to add load to a weak layer of surface hoar/crust/facets buried around 30 cm deep. It will be most sensitive to triggering where the overlying snow is deepest, dry and not capped by a more recent crust.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

In the warm weather on Thursday and Friday, loose wet avalanches were observed on steep solar aspects, average size 1 but up to size 2.

Over the past week and as recently as Thursday, several natural and human-triggered persistent slab avalanches size 1–2 have occurred across the region, failing on the late-January layer. Most of these avalanches have occurred near treeline.

Snowpack Summary

10 to 15 cm of new snow accumulates over mostly crusty surfaces. The old surface may remain dry on the highest north aspects and moist at low elevations.

A widespread weak layer is buried 20 to 30 cm deep. It formed in late January and consists of surface hoar on a melt-freeze crust, with facets below. Check out the snowpack test results on this layer in this MIN from Friday. This layer is expected to become even more concerning as it gets buried deeper.

The mid and lower snowpack remain well settled, with no significant concerns at this time.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Uncertainty is best managed through conservative terrain choices.
