Kernpunkte

New snow and strong southerly winds will build reactive storm slabs on Monday.

Storm slabs have the potential to step down and trigger large, destructive avalanches.

Lawinenprobleme

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1.5–2.5

    A buried layer of facets in the snowpack is expected to be more reactive in wind-affected thin rocky terrain features. Triggering of this layer is less likely where a supportive crust is present above.

    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit

    Größe
    1–2

    Moderate to heavy precipitation and strong southerly winds will build reactive storm slabs on Monday.

Confidence

Moderate

  • Deep persistent slabs could become more likely with the forecast weather.
  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

No new avalanches have been reported in the past few days.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Watch for fresh storm slabs building throughout the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
