Keep an eye on the wind and look for blowing snow at ridge crests. there is lots of unconsolidated snow available for transport. Great riding to be found in non-wind effected terrain!

Avalanche Summary

No new avalanches have been reported recently but observations have been limited.

Snowpack Summary

Up to 15cm of low density new snow exists in non-wind effected terrain. This new snow has likely formed new wind slabs in high alpine terrain and burried a variety of surfaces including old wind slab, facets and even bare ground.

In the mid pack it could be possible to find a thin layer of facets between old wind slabs. This layer recently produced sudden results in snowpack tests.

The height of the snowpack is variable. In areas lee of the prevailing wind, depths of up to 170cm can be found. At the lower elevation treeline terrain, snow depths decrease and are estimated at 60-90 cm.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Closely monitor how the new snow is bonding to the old surface.
