In sintesi

Human triggered avalanches are very likely.

Seek out simple terrain with no exposure to overhead hazard.

    New snow and wind will create new, reactive storm slabs.

    In some areas, they may bury older but still reactive wind slabs.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

A natural avalanche cycle is expected to occur throughout the duration of this storm.

Over the past few days, numerous storm slab and dry loose avalanches have been reported throughout this region, occurring at all aspects and elevations.

Snowpack Summary

Up to 70 cm of new snow has buried a previously faceted and wind-affected surface. New snow is expected to bond poorly to the previous surface.

Treeline snow depths exceed 300 cm.

Terrain and Travel Advice

  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
