Kernpunkte

Thin coverage in many areas over rocks and stumps remains a significant hazard. Good snow can be found in more sheltered areas near treeline.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    West winds have built wind slabs in lee areas and cross loaded terrain such as gully features. Triggering may be possible on steeper or unsupported features.

  • Persistent Slabs

    This layer of weak sugary snow is found in many areas  about 30 to 40cm from the ground. Triggering  of this  layer is more of a concern in shallower snowpack areas.

Weather Forecast

Continuing dry until late Thursday. Exciting to see as much as 20cm forecast for Friday as the cold arctic air mass meets with the westerly flow. Winds are expected to shift from west to north which will see reverse loading and a potential for increased avalanche hazard.

Snowpack Summary

A layer of faceted, weak crystals is found in most locations at about 30 to 40cm off the ground. Human triggering of this deeper instability may be possible in shallower snowpack  areas. Wind slabs are a concern in open areas at tree line and above.

Avalanche Summary

Very little recent activity.

Confidence

Intensity of incoming weather systems is uncertain
