    Stormy conditions persist, producing widespread storm slabs, particularly at higher elevations. Deeper and more reactive slabs are expected in wind-loaded, northerly terrain.

Confidence

Moderate

  • We are confident the likelihood of avalanche will increase with the arrival of the forecast weather.

Avalanche Summary

No recent avalanche activity has been reported in the past several days.

Natural avalanche activity remains possible with continued snowfall.

Snowpack Summary

Higher elevations have accumulated upwards of 60 cm of storm snow over the last few days, with more forecast falling Sunday.

A melt-freeze crust buried earlier in the week is now located approximately 40 to 80 cm below the surface at higher elevations, with wet, dense snow beneath it.

Deeper in the snowpack, a crust with facets, formed in mid-November, may exist 100 to 160 cm below the surface.

Total snowpack depths range from roughly 100 to 200 cm at higher elevations, thinning rapidly below treeline.
