Points saillants

Natural avalanches are unlikely but small, isolated rider triggerable wind slabs could exist.

Stepping out into big terrain with good travel habits and group management is appropriate.

    Small, isolated wind slabs could still exist near ridge crests in the alpine.

Confidence

Moderate

  • Uncertainty is due to rapidly fluctuating freezing levels.
  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches were reported on Wednesday but observations were limited.

On Tuesday, numerous natural, wet loose avalanches up to size 2 were observed. These avalanches occurred in steep, rocky south facing terrain.

Snowpack Summary

1 to 3 cm of new snow is expected by Friday morning. This new snow will overlie a variety of surfaces, including a crust on south-facing aspects and wind-affected snow on north-facing terrain.

The mid December crust is 150 to 250 cm deep. This crust is 30 cm thick and well bonded to the snow above.

In general, the snowpack is well settled and right-side up.

Weather Summary

Thursday Night

Mostly cloudy. 1 to 3 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Friday

Cloudy. 2 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1400 m.

Saturday

Mostly cloudy. 15 to 30 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Sunday

Mostly cloudy. 5 to 25 cm of snow. 40 to 60 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1400 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
