Moderate

Avalanche Summary

Small (size 1) natural and skier-triggered wind slabs were reported earlier in the week. Otherwise, no new avalanches have been observed.

Last week, large cornice failures in high north-facing alpine terrain notably did not propagate any weak layers on the slopes below. This is a good indicator of snowpack stability under current conditions.

Snowpack Summary

New snow is forecast to fall on Sunday, over widespread crusty surfaces on all but high north-facing alpine terrain, where snow is dry and likely wind affected.

There are no deeper concerns at this time.

Weather Summary

Thursday night

Broken cloud with flurries possible up to 3 cm. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -5 °C. Freezing level 1100 to 1500 m.

Friday

Broken cloud with sunny periods. 10 to 30 km/h east ridgetop wind. Treeline temperature -1 °C. Freezing level 2000m.

Saturday

Broken cloud with flurries starting in the afternoon, up to 5 cm possible. 10 to 30 km/h south ridgetop wind. Treeline temperature +1 °C. Freezing level 2200m.

Sunday

5 to 20 cm of new snow in high terrain. 20 to 50 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 2000m.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Dial back your terrain choices if you are seeing more than 20 cm of new snow.

Avalanche Problems

Storm Slabs

On Sunday, new snow and wind will form fresh slabs at upper elevations. Slabs are likely to be most reactive in wind-loaded lees and where they sit over a crust.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
