The likelihood and size of slab avalanches depend on the depth of a recently buried weak layer. Consider the consequences of a potential avalanche when placing yourself in the terrain.

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, 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 1–1.5 have occurred across the region, failing on the late-January layer. Most of these avalanches have occurred near treeline.

Snowpack Summary

A dusting of new snow falls over a thin surface crust or moist snow.

A widespread weak layer is buried 30 to 40 cm deep. It formed in late January and consists of surface hoar on a melt-freeze crust, with facets below. This layer is expected to remain a concern as it becomes buried deeper.

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

Weather Summary

Friday Night
Mostly clear skies. 30 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2300 m.

Saturday
Increasing cloud. 4 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1300 m.

Sunday
Mostly cloudy. 4 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1700 m.

Monday
Mix of sun and clouds. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -5 °C. Freezing level 1700 m.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
