Avalanche Summary

No recent avalanches have been reported, but field observations are limited this time of year.

If you head into the backcountry please submit a MIN report! They are extremely helpful to us in the early season when snowpack information is limited.

Snowpack Summary

As winds pick up Friday afternoon, 20-30 cm of fresh snow will likely be loaded into lee terrain features. This recent snow may sit over a surface crust on south aspects and low elevations.

80 to 100 cm of snow can be found in the alpine, with wind-loaded areas up to 150 cm. Many lower elevation areas remain below threshold for avalanches.

  • Avoid freshly wind loaded terrain features.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
