Snowpack Summary

Since Saturday, we have received between 10 and 15 cm of new snow. Although we have had a few episodes of moderate southerly winds, these seem to have had little effect on snow distribution and winds have been light since.In the alpine, this new snow rests directly on a crust that supports the weight of a skier, which is slightly more friable in the south. This new snow adheres relatively well to this crust. At the treeline and below, in areas protected from the wind, the new snow rests on a thin refreezing crust, followed by 10 to 20 cm of slightly denser snow that rests on the March 18 crust. The middle of the snowpack is well consolidated, and of increasing density, interspersed with several refreezing crusts from the last few weeks.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.


Wind Slabs

An icon showing Wind Slabs

Mild temperatures have allowed wind slabs to stabilize, but it would still be possible to find isolated slabs that have not adhered as well to the underlying crust, especially on the less heat-exposed north slopes.

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

Elevations: Alpine.
