Points saillants

New snow and wind will likely build wind slabs in the alpine.

Be cautious on Leeward features where fresh wind slabs are forming.

    As temperatures rise, large cornice falls will become a concern. They can potentially trigger slabs on the slopes below.

Avalanche Summary

No avalanche activity has been reported in recent days. If you do observe an avalanche, please share your observations on the Mountain Information Network.

Snowpack Summary

Wind has redistributed recent snow, forming pressed surfaces and wind slabs in open terrain while leaving 15-25 cm of settled snow in sheltered areas. A melt-freeze crust covers most solar slopes.

A buried surface hoar or crust layer, 40 to 60 cm deep, is variable in distribution. A December crust with facets, 100 to 150 cm deep on all aspects up to 1750 m, has shown no significant test results.

Snow depth ranges from 100 cm at highway elevations to over 300 cm in the alpine.

Monday

Mostly cloudy with 0 to 1 cm of snow. 30 to 50 km/h southeast ridgetop wind. Treeline temperature -4 °C.

Tuesday

Cloudy with 5 to 10 cm of new snow. 40 to 60 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 800 m.

Wednesday

Cloudy with up to 5 cm of new snow. 40 to 60 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
