Isolated pockets of wind slab may linger in steep terrain in the alpine.




Avalanche Summary

We didn't receive any reports of avalanche activity over the weekend. Looking forward, riders may find isolated pockets of small wind slabs lingering in lee terrain features near ridgetop.

Snowpack Summary

Northerly alpine slopes hold 10 to 20 cm of settled storm snow that overlies a hard melt-freeze crust. Isolated wind slabs may linger in steep northerly alpine terrain. All other aspects and everywhere below treeline have a hard surface crust.

The remainder of the upper snowpack is a mix of hard snow and crusts. The lower snowpack contains old weak layers that are currently dormant.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
