Points saillants

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.

    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.
