Kernpunkte

Expect a drastic change in snow stability when the predicted storm arrives. Tomorrow looks reasonable, but the storm could be early.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3
    These slabs are slow to bond. Expect them to be reactive for the next few days.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–3
    If these slabs react, expect a large propagation, and likely a step down to deeper layers.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–3
    Surface slabs and thin areas can potentially wake this layer up. Thin areas should be treated with caution.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

Tomorrow will see only trace amounts of snow as the incoming weather approaches. Winds will be light from the west and a daytime high of -11. We are expecting a storm to come in over the week-end. The snow amounts are uncertain right now, but we may see upwards of 30cm.

Avalanche Summary

On a snow survey flight today, only one new avalanche was noted. It was a sz2 that came out out of a crossloaded moraine feature. It had stepped down through the various windslabs.

Snowpack Summary

Widespread wind affect can be found in the alpine and open treeline areas. This translates to a hard slab resting on top of the very weak mid to lower snowpack. Not a lot of cracking or whumphing was noted today, but hollow sounding slabs are very common. On east aspects there are still pockets of wind sifted snow that offers some good skiing. Below treeline is the same old story. Mostly a weak and un-supportive snowpack.
