Avalanche Summary

Numerous natural and rider triggered storm/wind slab avalanches up to size 2 were reported on all aspects in the alpine on Wednesday.

Snowpack Summary

Up to 40 cm of recent snow can be found at upper elevations and is settling rapidly with intense solar radiation and warm temperatures. Previous southwest wind formed slabs on lee features in the alpine.

The recent snow sits above a crust in most areas. The exception is on northerly aspects above 2200 m where it overlies dry snow.Expect difficult travel at lower elevations with thin snow coverage.

Terrain and Travel Advice

  • Remote triggering is a concern, watch out for adjacent and overhead slopes.
  • Be alert to conditions that change with aspect and elevation.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
  • Use small low consequence slopes to test the bond of the new snow.
