Use good travel habits and avoid shallow, rocky start zones. Watch for unstable snow on isolated terrain features, and in extreme terrain.
There is no avalanche activity to report in the last few days.
By Thursday afternoon, up to 5cm of new snow may have fallen over a crust or moist snow on all aspects except north. On high northerly slopes, last week's snowfall may overlie facets and surface hoar to mountain tops.
The middle of the snowpack is generally well-settled and strong.
A weak layer of large facets is found near the base of the snowpack. This layer is still a concern in shallow snowpack areas.
Mostly clear. No new snow expected. Moderate southwest ridgetop wind. Freezing level at valley bottom.
Mostly cloudy, possible sunny pockets in the morning. 0-2 cm of snow expected. Moderate to strong southwest ridgetop wind. Freezing level rising to 1100m. High of -7 °C at treeline.
Cloudy. 0-10 cm of snow expected. Moderate southwest ridgetop wind. High of -3 °C at treeline. Freezing level at valley bottom in the morning, rising to 1100 m. High of -7 °C at treeline.
Mostly cloudy. Possible trace of snow expected. Light northwest ridgetop wind. Freezing level at valley bottom in the morning, rising to 1100 m. High of -7 °C at treeline.

Terrain and Travel Advice
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Deep Persistent Slabs
A weak layer of facets exists near the base of the snowpack. The likelihood of human triggering is low given the layer's depth.
Aspects: All aspects.
