Avalanche Summary

A rider triggered size 1.5 wind slab was reported on a northwest aspect in the alpine on Saturday. See MIN.

If you go into the backcountry, please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

Up to 15 cm forecast snow and southwest wind may form wind slabs on lee features at treeline and above. Recent wind has varied in direction, so watch for wind slabs on all aspects.

Below the new snow is a crust everywhere except true north facing terrain at upper elevations.

The facet/crust layer that produced large avalanches during early March is down 80 to 150 cm. It is currently considered to be dormant in most locations.

Many areas below treeline are either snow free or have very thin snow coverage. Expect difficult travel at lower elevations.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
