Snowpack Summary

15-25cm of new snow buries old wind slab in the alpine and a thin layer of facets. Excellent snow quality found in sheltered locations.

The deep persistent weakness near the base of the snowpack consists of rounding facets and a decomposing crust in some locations.

Weather Summary

Monday will have a mix of sun and cloud with a chance of isolated flurries. Alpine temps will range from -12 to -18 with ridgetop winds 15-25km/hr from the South West.

Small amounts of snow for Tuesday and Thursday.

Terrain and Travel Advice

  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Loose avalanches may start small but they can grow and push you into dangerous terrain.
  • Use appropriate sluff management techniques.
