In sintesi

Recent snowfall is rapidly warming. Keep an eye out for wet loose activity as we transition to a period without overnight freezing.

Wind slabs may be found in isolated alpine terrain features.

    Variable winds have redistributed storm snow. This problem is possible in isolated alpine features.

    Previous storm snow blankets all terrain and is warming up quickly. We expect to see a widespread wet loose cycle.

Snowpack Summary

55 cm of last week's storm snow has settled down to 30 cm. Under it sits a melt freeze crust. The atmospheric river crust is down 50-70 cm. The mid and lower snowpack are well settled.

Terrain and Travel Advice

  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Wind slabs are isolated, but may remain reactive.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of warming will affect the snowpack.

Avalanche Summary

Numerous wet loose avalanches, up to size 2 were observed on Saturday. Limited field observations.
