In sintesi

Snow is on the way for the weekend! Until then, practice good travel habits and use caution around terrains traps.

Confidence

High - We have a good understanding of the snowpack structure and confidence in the weather forecast

Avalanche Summary

Avalanche activity over the past few days has been limited to small (size 1) slab and loose avalanches in steep alpine terrain.

Snowpack Summary

5-15 cm of fresh snow sits above hard wind-affect snow and melt-freeze crusts. Some small surface hoar may be found above the crust in sheltered terrain. The snowpack below is well consolidated, with a crust/facet layer found near the bottom of the snowpack. It is currently considered dormant, but could become active later this season as discussed in this forecaster blog.

Terrain and Travel

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
