Avalanche Summary

On Wednesday a natural avalanche cycle occurred with storm and wind slab avalanches up to size 3. Check out this MIN from the Tantalus.

Numerous wet loose and dry loose avalanches were also observed in the region on Wednesday.

Snowpack Summary

A new crust can be found at or near the surface on all but high north facing terrain. The alpine is variably wind effected from moderate to strong northeast winds with previous southerly winds.

Several crusts can be found in the upper snowpack. A well settled snowpack exists below.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Be alert to conditions that change with aspect and elevation.
  • Minimize your exposure time below cornices.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
