If you go out, consider writing a MIN report.

Avalanche Summary

Reports are very limited at the moment but the storm slab is sensitive to human triggering and natural avalanches are possible.

Snowpack Summary

Recent snowfall amounts are around 40 to 50 cm. The top of the snowpack is generally soft and gets firmer as you go down. A layer of surface hoar that has been reported in open areas at treeline and below is buried 60-70 cm deep. The bottom of the snowpack has a crust from early November that is just above the ground. Snowpack depth is 130 - 180 cm at treeline.

Terrain and Travel Advice

  • Don't let storm day fever lure you into consequential terrain.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
