    Cornice failures are destructive on their own and often break farther back from the ridgeline than expected.

Confidence

Moderate

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Pinwheeling was observed on Friday, and on Thursday several naturally triggered wet loose avalanches up to size 2.5 were reported on steep, rocky, southerly aspects in the alpine with high temperatures and strong sunshine.

Observations from this region are very limited. Please consider submitting a MIN to let us know what you're seeing out there.

Snowpack Summary

A lack of overnight refreeze and light rain will keep the snow surface moist/wet to mountain top.

The mid and lower snowpack are generally well-settled and strong in most areas, with numerous crusts throughout. Snowpack depth tapers rapidly at lower elevations.
