Avalanche Summary

No recent avalanche reports.

Data is very limited in this region. Please submit your MIN (Mountain Information Network)

Snowpack Summary

15 to 30 cm fresh snow accumulated over the weekend. At upper elevations southwesterly winds redistributed snow to lee features. Fresh snow covered older snow in most terrain and surface hoar in isolated sheltered locations.

A surface hoar layer is now buried 30 to 60 cm and is most prevalent from 1700 to 2200 m. This layer has not been reactive to skier traffic, however we will continue to monitor it as more snow loads above it. Where there's no surface hoar, a crust is found at this interface.

There are no deeper layers of concern.

Weather Summary

Sunday night

Cloudy with stary breaks. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -14 °C.

Monday

Cloudy with sunny breaks. 5 to 15 km/h southeast ridgetop wind. Treeline temperature -14 °C.

Tuesday

Mostly cloudy. 5 to 15 km/h southeast ridgetop winds. Treeline temperature -10 °C.

Wednesday

Snow, 10-20 cm. Increasing southwest ridgetop winds. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Investigate the bond of the recent snow before committing to your line.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

Avalanche Problems

Wind Slabs

Investigate for wind-loaded pockets, especially around ridges and open bowls.

A currently unreactive surface hoar layer is buried 30 to 60 cm. We are tracking this layer as reactivity may increase as more snow loads into a slab above.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
