Rainfall and high freezing levels are going to transform the snowpack. Watch for signs of instability as the snow begins to saturate.

    Wet loose avalanches are possible at all elevations as freezing levels rise. Expect them to be touchy in areas where a melt-freeze crust lays beneath the surface snow.

Confidence

Moderate

Avalanche Summary

Wet loose avalanches continue to be observed in steep terrain at treeline and below.

Snowpack Summary

In the alpine, up to 25 cm of wind redistributed snow sits on a decomposing melt-freeze crust. At treeline and below, 10 cm of rapidly settling moist snow sits on a crust from Tuesdays warming event.

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

  • 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.
