Avalanche conditions may become increasingly reactive Friday afternoon as the wind ramps up and loads fresh snow into leeward terrain features.
Confidence
Moderate
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.

Terrain and Travel Advice
- Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
- Avoid freshly wind loaded terrain features.
- Wind slabs may be poorly bonded to the underlying crust.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
