Points saillants

Strong solar radiation will likely impact the surface snow.

Watch for unstable snow on steep terrain features, especially when the snow is moist or wet.

    Small wet loose avalanches will become likely with daytime heating and solar exposure. Be cautious around steep sun-exposed slopes where recent snow overlays a melt-freeze crust.

Moderate

Avalanche Summary

No recent avalanche activity has been reported.

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

Snowpack Summary

At upper elevations, 10 to 15 cm of new snow has accumulated over moist snow or a crust on all aspects, except north-facing alpine slopes where dry remained. Small pockets of wind slabs have likely formed in all alpine terrain with recent wind from different directions. At lower elevations, a moist snowpack or a surface crust is found.

The mid and lower snowpack are generally well-bonded. The height of snow is about 200 cm at treeline.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
