    Cornices will weaken with daytime warming. A cornice fall could trigger slabs on slopes beneath them. Daytime warming will also produce small loose wet activity.

Avalanche Summary

We haven't received any recent reports of avalanche activity.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

A dusting of dry snow is found over a hard melt-freeze crust. This snow will melt with daytime warming. Old wind slabs may linger in lee terrain features near mountain tops.

Two weak layers that formed in February and March are found in the middle of the snowpack. These layers are currently dormant, but they could be triggered with a large load such as a cornice fall.

Terrain and Travel Advice

  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
