Avalanche Summary

Over the past couple days several natural storm and wind slab avalanches up to size 1.5 were observed in the region , Most of this avalanche activity was on north and east aspects. A small natural glide slab was also reported. 

Snowpack Summary

New wind slab will likely form on northerly aspects throughout the day on Saturday. a melt-freeze crust exists on sun-exposed aspects.  

In the north of the region, a crust/facet interface from February sits 30-60 cm deep and had been most problematic on north to northeast aspects around 1900-2100 m. This layer produced a number of avalanche in early March but is now considered dormant. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
