Avalanche Summary

There were a few skier controlled size 1 storm slab and dry loose avalanches reported from steep terrain on Monday.

Snowpack Summary

10 - 20 cm of new snow has accumulated over a crust at most elevations. Below 1500 m surface snow is likely moist or wet.

A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets sitting on a crust is buried 80-100 cm deep. While previous warming and subsequent cooling have likely helped to strengthen these layers, we will continue to monitor them for signs of reactivity.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs are most reactive during their formation.
