Kernpunkte

Manage the uncertainty by choosing low-angle slopes free from overhead hazards.

We are uncertain about the distribution of buried weak layers in the top metre of the snowpack.

    Wind slabs may step down to buried weak layers. Avoid wind-loaded features.

  • Persistent Slabs

    Several persistent weak layers of surface hoar, facets or crusts may be buried in the top meter of the snowpack. Wind slabs could step down to these layers, causing larger-than-expected avalanches.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

No new avalanches have been reported on Tuesday or Wednesday.

On Monday, there was a natural avalanche cycle, mostly size 2, on solar slopes.

On Sunday, numerous natural avalanches up to size 3 were observed on solar aspects with strong sun. Several large (size 2) naturals were observed from wind-loaded alpine terrain.

Snowpack Summary

Up to 20 cm of new snow has fallen at upper elevations in the past two days. Strong south and west winds will have redistributed this snow into deeper deposits in wind-loaded areas. This new snow overlies a melt-freeze crust on solar aspects and lower elevations, and wind-affected layers at higher elevations.

A couple of persistent weak layers buried in the last week may exist in the upper 30 to 60 cm of the snowpack. These consist of surface hoar, facets and crusts.

Buried around 60 to 100 cm is a prominent, persistent weak layer of facets and crust from early February.

The remaining snowpack appears to be strong and well-bonded.

Weather Summary

Wednesday Night

Mostly cloudy. 1 cm of snow. 25 km/h west ridgetop wind. Treeline temperature -4 °C.

Thursday

Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -6 °C.

Friday

Mostly cloudy. Up to 5 cm of snow. 40 to 80 km/h west ridgetop wind. Treeline temperature -4 °C.

Saturday

Mostly sunny. 1 cm of snow overnight. 80 to 100 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 2200 m.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Be careful as you transition into wind-affected terrain.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
