Happy New Year! Have a safe start to this new year by avoiding wind-loaded areas and practicing good travel habits. Recently formed wind slabs overlie a slick crust and are may remain reactive to human triggering.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

This week, 15-40 cm of storm snow was accompanied by strong southwest winds, creating hard wind-affected surfaces in open areas, and wind slabs in lee terrain features. This new snow overlies a rain crust formed earlier in the week.

The mid-snowpack is well-settled. The lower snowpack consists of several crusts with weak faceted crystals above and below that are beginning to heal and bond to each other.

Snowpack depths are roughly 140 to 180 cm at treeline.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Keep in mind the crust offers an excellent bed surface for avalanches.
  • Use ridges or ribs to avoid areas of wind loaded snow.

Avalanche Problems

Wind Slabs

Strong southerly winds have redistributed 15 - 30 cm of new snow into deep deposits of wind slabs at higher elevations. These wind slabs may remain reactive to human triggering, particularly where they overlie a slick crust.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
