Avalanche Summary

No new avalanches have been reported. Looking forward, snow and wind forecast for the next few days will likely promote a new round of storm slab activity.

Snowpack Summary

A light dusting of snow covers a medley of surfaces which include stubborn wind slabs and wind-scoured exposed crust in the alpine, and soft unconsolidated snow in sheltered areas at treeline and below. Variable amounts of settled and facetted storm snow (up to 100cm around the Coquihalla and closer to 40cm in the Duffey area) overlie a widespread melt-freeze crust that was buried on December 15th. Recent snowpack tests have ranged from no results, to moderate to hard resistant results on this layer.Beneath the December 15th layer the snowpack is well settled.
