Kernpunkte

While it is becoming less likely to trigger buried weak layers, if it does happen, the consequences could be severe

Lawinenprobleme

    Buried surface hoar is likely becoming harder to trigger, however, consequences remain high if triggered.

    Basal facets remain a concern, particularly in steep, rocky terrain characterized by varying snowpack depths ranging from thin to thick.

Confidence

Moderate

Snowpack Summary

The upper snowpack is generally well-settled and consolidated with no significant layers of concern.

A layer of surface hoar down roughly 50 to 90 cm remains problematic despite a lack of recent signs of reactivity. A hard crust above this layer is likely protecting it from human-triggering at lower elevations.

Weak basal facets characterize the bottom of the snowpack.

Weather Summary

Tuesday night

Mostly cloudy with no precipitation, southwest alpine winds 10 to 20 km/h, treeline temperature -5 °C.

Wednesday

Cloudy with up to 5 cm of snow, southwest alpine winds 10 to 20 km/h, treeline temperature -5 °C.

Thursday

Cloudy with trace snow amounts, southwest alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Friday

Cloudy with trace snow amounts, southwest alpine winds 10 to 30 km/h, treeline temperature -7 °C.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Keep in mind that human triggering potential persists as natural avalanching tapers off.
  • Uncertainty is best managed through conservative terrain choices at this time.
