Kernpunkte

Spring convective activity continues to deliver variable amounts of new snow to the region. This may increase the avalanche hazard locally.

    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.

Avalanche Summary

No new avalanche activity reported

Don't forget to post avalanche observations to the MIN.

Snowpack Summary

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.

Weather Summary

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.
