Kernpunkte

If there is a thick crust, avalanches are unlikely.

Spring conditions can change rapidly. Read about the 4 likely scenarios here.

Lawinenprobleme

  • Cornices

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

    Cornices may fail with warm temperatures and sunshine.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit

    Wet loose avalanches are likely when there is no crust present.

Confidence

Low

Avalanche Summary

No new avalanches have been reported since the weekend, however, data is limited.

On Friday, skiers remotely triggered a slab on a northeast lee ridge feature at treeline near Mt. Fisher.

Snowpack Summary

5 to 15 cm of snow sits on a crust up high or moist snow below 2000 m. High alpine north facing slopes may still hold dry snow above a thick crust from late March.

The snowpack is quickly disappearing below treeline.

There are no other layers of concern.

Terrain and Travel Advice

  • Avalanche danger will increase as the surface crust breaks down.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
