Highlights

The forecast is moderate which means human triggered avalanches are possible. Take the time to investigate the wind slabs and density changes as you approach treeline and the alpine.

    Lets think east side of the road vs west side of the road for a second. On the west side, windslabs are present at treeline and above. They are weak from the cold spell and will be more likely to trigger on steep convex rolls. Conversely, the east side of the road is much shallower and has a more sensitive and unpredictable feel to it. Choose supported terrain with no terrain traps.

Weather Forecast

Wednesday is expected to be a mixed bag of sun, cloud and flurries. Temperatures will rise to -10c in the alpine and then dropping Tuesday night to -22c. Winds will be 20-30km/hr from the west.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

The alpine has widespread wind slabs in the upper 40cm that are still providing good skiing as long as they are not too dense. Take the time to investigate these wind slabs so as to not be surprised in the density change. Cracking around your skis is a good indicator of this density change. The Jan 29 interface is down about 50-60cm and is producing a shear.

Terrain and Travel

  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.
  • Carefully evaluate steep lines for wind slabs.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
