Kernpunkte

Start early and plan to be away from sunny slopes before they heat up.

The danger is likely low in the morning and will rise with daytime warming.

Lawinenprobleme

  • Cornices

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

    Cornices are unpredictable and are more likely to fail in warm periods. Avoid travelling on or under them.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    1–2

    If the sun comes out, it will likely trigger wet loose avalanches on steep sunny slopes.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

There have been many small, natural wet loose avalanches over the past three days. As well as a few natural cornice failures.

Snowpack Summary

A new surface crust has likely formed to mountian top on slopes that face the sun, and to around treeline on shaded slopes.

A thick crust is buried 30 to 40 cm deep, which makes triggering unlikely for any weak layers that persist below it in the upper snowpack.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.

Terrain and Travel Advice

  • Start your day early and be out of avalanche terrain during the heat of the day.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
