Points saillants

A widespread surface crust is creating stable avalanche conditions, but is making travel challenging.

Problèmes avalancheux

    Probabilité

    Taille
    1.5–2.5

    In high alpine terrain where the surface crust may not exist or be unsupportive, persistent weak layers may remain human-triggerable.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Carefully evaluate big/extreme terrain features before committing to them, it's not full "go" time yet.
  • Expect shallow snow cover that barely covers ground roughness.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Trace amounts of dry snow have begun to accumulate atop a widespread hard crust. In general, the crust is strong and supportive to travel on.

In the midpack, a weak facet layer persists, but has become unlikely to trigger with a supportive crust above.

Areas in the east of the region are largely characterized by a shallow and faceted snowpack.
