Avalanche Summary

No new reports of avalanches since Friday when natural and remote triggered wind slabs size 1.5-2 were observed on north facing slopes in the alpine. Wind slabs appear to be less sensitive according to this well-travelled group's MIN report from Saturday.

Snowpack Summary

Alpine surfaces are mainly wind-affected, but soft snow can still be found in wind-sheltered terrain. A spotty layer of surface hoar may sit below recent snow, buried around 20 to 30 cm deep.

Below 1500 m, a thick melt-freeze crust is buried 50-100 cm deep.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
