Points saillants

Assess surface conditions as you gain elevation. Where dry snow is found, small wind slabs are likely . Where the snow surface is wet, loose avalanches are possible.

    New small wind slabs will likely build through the day with continued snow and wind.

    With continued daytime warming and high freezing levels, loose wet avalanches are possible out of steep terrain.

Moderate

Avalanche Summary

Small wet loose avalanches have been reported in the past few days. This type of avalanche activity could continue in steep terrain as we continue to go through a cycle of rising and falling freezing levels.

Snowpack Summary

In the alpine precipitation has been falling as snow and  forming wind slabs on northerly aspects. At treeline and below a crust will likely be found on the surface that may break down throughout the day and become moist.

The mid and lower snowpack contain several crusts that are not concerning. The snowpack remains shallow for this time of year.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
