Lo esencial

Forecast snow and wind overnight on Monday are expected to form fresh storm slabs reactive to human triggers, especially in wind-affected terrain.

Make conservative terrain choices, and use small slopes, with low consequence to test the bond of the new snow.

Snowpack Summary

Forecast 15-25 cm of snow and strong southeasterly winds overnight Monday are expected to form fresh storm slabs reactive to human triggers, especially in wind-affected terrain.

Below the early December crust layers, the snowpack is generally well-settled and strong. 

Terrain and Travel

  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
  • Shooting cracks, whumphs and recent avalanches are strong indicators of an unstable snowpack.
  • Use small low consequence slopes to test the bond of the new snow.
  • Avoid terrain traps where the consequence of any avalanche could be serious.
