Recent storm slabs are likely to remain reactive. Stick to conservative terrain and avoid overhead hazard.
Summary
Confidence
Moderate
Avalanche Summary
Observations have been limited by poor visibility through the storm. Natural and explosive triggered avalanches up to size 2 have been reported over the weekend; storm and wind slabs at upper elevations and loose wet below treeline.
Looking forward, human-triggered avalanches will remain likely as natural activity subsides.
Snowpack Summary
30 to 60 cm of recent storm snow overlies hard surfaces in wind exposed areas, facets and surface hoar in sheltered terrain, and crust on low elevation solar aspects.
Two layers of surface hoar from January can be found in the top meter of the snowpack.
A layer of facets on top of a crust from early December is buried 100 to 200 cm deep. This layer is generally not a concern in this region.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Keep in mind that human triggering may persist as natural avalanches taper off.
- Be aware of the potential for large avalanches due to buried surface hoar.
Problems
Storm Slabs
Storm slabs sit on a weak interface and will likely remain reactive.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
Two surface hoar layers can be found in the top meter of the snowpack in sheltered terrain. They have been unreactive recently, but rapid change due to new snow and warm temperatures may wake them up.
Aspects: All aspects.
Elevations: Alpine, Treeline.
