The alpine rating is Deep Persistent Slabs., the treeline rating is , and the below treeline rating is Known problems include
Spring convective activity continues to deliver variable amounts of new snow to the region. This may increase the avalanche hazard locally.
No new avalanche activity reported
Don't forget to post avalanche observations to the MIN.
New snow sitting on top of a sun crust at all elevations on solar aspects, with facets on polar aspects. The mid-pack consists of multiple layers of dense wind-affected snow, sun crust, and facets. Depth hoar and basal facets make up the base of the snowpack. Snow depth varies ranges from 60-170cm.
Little change is expected in the weather for the next few days. Light variable winds may transport localized new snow from convective flurries. Freezing levels to rise daily up to 1500m. Temperatures are expected to be seasonal with cold nights and a daytime high of -7 C in the alpine.
Terrain and Travel Advice
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Deep Persistent Slabs
The bottom of the snowpack is inherently weak with well-developed Facets and Depth Hoar. Large triggers like cornices can still initiate this deep persistent slab so be mindful of your overhead hazard and keep in mind that human triggering remains possible in thick to thin snowpack areas.
Aspects: All aspects.
Elevations: Alpine, Treeline.
