Lo esencial

Stick to conservative, low consequence terrain and give the storm snow time to settle.

Recent storm snow has weakened a concerning upper snowpack, human triggered avalanches are likely.

Problemas de aludes

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad

    Several weak layers in the snowpack may be rider triggerable. These layers exist on all aspects and elevations.

  • Storm Slabs

    Storm slabs are expected to remain sensitive to human triggering. Storm slabs may step down to deeper layers.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

Numerous storm and persistent slab avalanches up to size 3 were reported in the region over the past 4 days. Avalanches have been triggered accidentally, naturally, and remotely. These avalanches have occurred on all aspects and elevations but most activity has been on north and east facing terrain.

Check out this MIN report and this one for more details.

Snowpack Summary

Up to 20 cm of fresh snow accompanied by strong southwest wind has formed deeper deposits on north and east aspects. In sheltered terrain it will overlie a layer of surface hoar or a sun crust. The snow surface is expected to become moist on sun exposed slopes.

A couple concerning weak layers exist in the upper snowpack:

  • 60 to 80 cm deep, there is a supportive crust on south-facing terrain. On north-facing terrain, this layer maybe a breakable crust or surface hoar.

  • The late January layer is buried 70 to 120 cm deep. It consists of a crust with facets or surface hoar above it.

The mid and lower snowpack is well settled.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Keep your guard up at lower elevations. Storms slabs have been reactive at all elevations.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
