The change is here!

30+ cm of snow has fallen in the last 48 hours along the spray.

This has triggered a natural avalanche cycle. Conservative terrain choices are paramount while the snowpack adjusts with the change.

Avalanche Summary

Forecasters out today heard continuous rumbles of loose dry avalanches off steep cliff features. There was also a small soft slab in a gully feature below treeline. We expect there was natural cycle to some degree today. Zero visibility throughout the day so no direct observations while travelling.

Snowpack Summary

Friday through Saturday produced 30+ cm of snow with strong winds. The spray valley feels like winter again. This now overlies all of the previous layers from the whole of January. Hard wind affected surfaces, Facets and crusts on solar aspects. Below this is a mostly a faceted snowpack to ground. The big change is in your mindset. We are leaving the green brick, so step back, and evaluate the changing avalanche danger.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Be careful as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Dial back your terrain choices if you are seeing more than 20 cm of new snow.
