Avalanche Summary

No new avalanches have been reported in the region. Please submit your observations to the Mountain Information Network.

Snowpack Summary

In most places rain from Saturday has likely made the surface snow moist or wet except for the high elevation alpine. If there has been a good overnight freeze, there may be a supportive crust on the surface. The mid and lower snowpack pack are likely a mixture of moist snow and crusts. Below treeline the snowpack has melted or is isothermal.

Avalanche Problems

Loose Wet

Expect loose wet avalanches to run in steep terrain facing the sun with clear skies and a high freezing level forecast for Monday. Expect surface crusts to break down quickly with overnight temperatures that have been near zero or above freezing.

  • Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
  • A moist/wet snow surface, pinwheeling, and natural avalanches all indicate increased instability.

Aspects: East, South East, South, South West, West.

Elevations: Alpine, Treeline.
