Kernpunkte

Great riding in sheltered locations.

Flurries not enough to refresh your favourite line this weekend but, the cold temps have likely faceted the tracks!

Be cautious near overhead features, avalanches can run far on the Dec crust, TL and below.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2.5

    Building wind slabs due to continued small snow inputs and steady moderate wind. Careful assessment is required with local terrain influences.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1.5–3

    This layer is a rain crust up to 1950m and reactive to large loads. Typically this layer is down around 40cm.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely
    Größe
    1.5–3

    Natural deep avalanches are getting less frequent yet it remains a low probability and high consequence event if you push your luck.

Weather Forecast

Friday: Cloudy with sunny periods and isolated flurries. Trace. Temp: High -8 °C. Wind W:15-35 km/h.

Saturday: Cloudy with sunny periods and isolated flurries. Trace. Temp: Low -22 °C, High -14 °C. Wind west: 20 km/h gusting to 55 km/h.

Sunday: Mainly cloudy with isolated flurries. Trace. Temp: Low -13 °C, High -8 °C. Wind west: 20-30 km/h.

Snowpack Summary

Cold temperatures continue to promote faceting. Continued wind slabs building in deposition zones. The mid-pack is supportive with a questionable interface down close to 40cm, which has questionable reactivity below 1900m. Basal faceting continues near or on the ground.

Avalanche Summary

No new avalanches observed or reported today, poor afternoon visibility.
