Avalanche Summary

Nothing noted or reported today. 

Snowpack Summary

Up to 10cm of new snow in the past 24 hours, with less in the Eastern ranges (such as Highwood Pass). This overlies extensive amounts of tracks in the popular areas and wind slab most everywhere else. Alpine areas are extensively wind damaged with hard wind slabs present in most places. The November crust (now buried 20 to 30cm) tapers out quickly above 2200m.

Terrain and Travel

  • Approach lee and cross-loaded slopes with caution.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
