Highlights

As the surface crust breaks down the likelihood of triggering an avalanche will increase.

It is uncertain how the continued warmth will affect the snowpack so watch for signs of instability.

Avalanche problems

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–4

    A layer of surface combined with a crust may become easier to trigger as temperatures warm and the sun comes out.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2.5

    Use caution on steep south aspect terrain features where snow is becoming moist and unconsolidated. As day time temperature rise and the sun comes out, expect avalanche triggering to become possible to human triggers.

Confidence

Moderate

  • Uncertainty is due to how quickly the snowpack will recover and gain strength.
  • Uncertainty is due to rapidly fluctuating freezing levels.

Avalanche Summary

January 15

  • Large (up to size 3) explosive triggered persistent slab avalanches were reported near Shames.

  • Other operations in the region reported avalanche activity decreasing with cooler temperatures.

January 14

  • A widespread natural avalanche cycle (up to size 4) was reported throughout all elevations and aspects caused by the snowfall, rainfall and warming of the atmospheric river.

Snowpack Summary

On the surface there is a crust. In terrain exposed to the wind, small wind slabs are forming on lee aspect terrain.

At treeline, very warm and wet surface snow has now become a melt freeze crust. Expect this crust to be supportive to ski and foot weight but may start to break down as the warm air lingers.

A layer of large surface hoar is buried 90 to 150 cm in sheltered treeline features. The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 250 cm to 450 cm.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
