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

20-30 cm of snow buries a variety of wind-affected surfaces and possibly 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.

Weather Summary

Terrain and Travel Advice

  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.

Avalanche Problems

New snow and wind are forming fresh slabs. These storm slabs may be especially reactive where they sit over a crust.

Aspects: All aspects.
