Avalanche Summary

No new avalanches reported since Sunday. Incoming precipitation and wind will create small windslabs in alpine and treeline elevations.

Observations remain limited in this region. If you head into the backcountry, please consider sharing your observations to the Mountain Information Network (MIN)!n the alpine and treeline elevations.

Snowpack Summary

New snow will likely fall on surface hoar in sheltered locations and surface facets. 10 to 30 cm of old snow overlies a hard melt-freeze crust up to 1600 m and isolated pockets of surface hoar crystals in wind-sheltered openings at treeline and above.

There are currently no deeper layers of concern.

Weather Summary

Friday night

Cloudy with snow, 0 to 5 cm. 20 to 40 km/h south ridgetop wind. Treeline temperature -6 °C.

Saturday

Cloudy with snow, 0 to 5 cm. 40 to 60 km/h south ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Investigate the bond of the recent snow before committing to your line.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Avalanche Problems

Wind Slabs

New slabs may develop where new snow has been deposited by wind. Older slabs are most likely to be triggered in sheltered lee features in the lower alpine where pockets of deeper snow have been deposited over a layer of surface hoar.

Aspects: North, North East, East, South East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
