Kernpunkte

The avalanche danger is Low as long as the melt freeze crust remains intact.  The danger will rise rapidly as the crust deteriorates with sun exposure and daytime heating.  Check out this link for more info about the spring avalanche condition.

Lawinenprobleme

  • Storm Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    Slabs that formed on the April 22 crust have not been reactive lately. It is still possible to trigger these slabs on steep terrain below ridgelines or convex features.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Loose wet avalanches can be expected on sunny south facing aspects as temperatures rise during the day.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–3
    Cornice failures or triggering from thin spots have the potential to initiate deep avalanches. Depending on aspect, these could be a wet or dry slab characteristic.

Weather Forecast

Spring conditions are here with warming daytime temperatures, sunny skies and cool nights. These conditions will develop a supportive overnight crust that will breakdown rapidly by late morning. 

Snowpack Summary

There is rain crust from the valley bottom to 2,350m and a sun crust into Alpine on solar aspects. Settled wind slabs are on NE aspects from 2,000 m to the alpine. Moist and wet snow exists below the crust extending into the alpine on solar aspects. The mid-pack is solid on North aspects. Large cornices.

Avalanche Summary

No field trips today.

The weather pattern is stable on Monday
