Highlights

Continuously assess conditions as you move through terrain.

Where the snow surface is dry, wind slabs are possible; where it is wet, loose wet avalanches are possible.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    Rider triggerable wind slabs can still be found on north and east aspects at upper treeline and in the alpine.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    Wet loose avalanches are possible on steep terrain when the snow surface feels slushy or wet.

Confidence

Moderate

  • Uncertainty is due to rapidly fluctuating freezing levels.

Avalanche Summary

Explosives and ski cutting have produced small dry loose and wind slab avalanches in steep features over the past couple days.

Snowpack Summary

Surface snow is variable, on steep solar facing slopes moist snow is expected and on north facing slopes above 2000 m 20 to 40 cm of dry, wind affected snow can be found.

Within the upper snowpack a surface hoar layer can be found roughly 30 cm deep in sheltered treeline terrain.

A crust buried on December 16th is roughly 150 cm deep. Above 2200 m, this crust is absent and an old crust complex and faceted snow from November is found at the base of the snowpack.

Weather Summary

Tuesday Night

Mostly clear skies. 30 km/h southwest ridgetop wind. Treeline temperature 2°C. potential for below freezing layer near valley bottoms.

Wednesday

Mostly sunny. 30 km/h southwest ridgetop wind. Treeline temperature 2°C. Freezing level 2000 m.

Thursday

Mix of sun and clouds. 20 km/h south ridgetop wind. Treeline temperature 2°C. Freezing level 1900 m.

Friday

Mostly cloudy. 5 to 10 cm of snow at treeline and above, rain at low elevation. 30 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
