Use extra caution at treeline where surface hoar is more likely to be preserved.
Reports are coming in indicating that this layer is sensitive to human triggers.

Avalanche Summary
No recent avalanches have been reported in our region.
Consider supporting your backcountry community by submitting your own observation in a MIN report.
Snowpack Summary
Up to 30 cm of recent low density snow could have formed storm slab in the alpine and treeline on terrain features that are above threshold for avalanches. This new snow overlies large surface hoar in sheltered terrain.
At treeline, the height of snow ranges from approximately 60 to 90 cm. Below this elevation, snow height decreases drastically. The snowpack at all elevations is very shallow and contains many potential hazards just beneath the surface.
Weather Summary
Saturday Night
Partly cloudy with trace amounts of new snow expected, south alpine wind 25 to 40 km/h, treeline temperature -8°C.
Sunday
Mostly cloudy, up to 10 cm of new snow expected, southwest alpine wind 40 to 60 km/h, treeline temperature -6°C.
Monday
Mostly cloudy with up to 10 cm of new snow expected, southwest alpine wind 25 to 50 km/h, freezing level up to 1700 m.
Tuesday
Cloudy , 10 to 20 cm of new snow expected, south alpine wind 40 to 60 km/h, freezing level rising to 2100 m.

Terrain and Travel Advice
- Storm slab size and sensitivity to triggering will likely increase through the day.
- Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Problems
Storm Slabs
New snow is forming rider triggerable storm slabs. The most reactive slabs will be found at treeline where surface hoar is most preserved.
