Points saillants

Take care around ridgelines where wind slabs may linger.

Minimize your exposure to sun affected slopes. Sunshine and rising temperatures will increase the potential for wet avalanches.

    Recent snowfall and southwest winds may have formed wind slabs in lee terrain features in the alpine and treeline.

    Expect wet slab and wet loose avalanches on steep, sun affected slopes as temperatures rise. Avalanches are expected to initiate easily on the crust below.

Avalanche Summary

No new avalanches were reported in this region over the past few days. However, field observations are currently very limited.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network, observations are limited.

Snowpack Summary

Up to 10 cm of settling storm snow sits over old snow surfaces, and a crust on sun affected slopes. On north facing slopes near ridgelines, deeper deposits of snow can be found - while south facing slopes may hold hard, wind pressed surfaces or a crust.

Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
