Kernpunkte

Choosing smart terrain is the name of the game right now. Choose supported terrain, without terrain traps. Good skiing can be found in sheltered areas at treeline.

Lawinenprobleme

    These are slowly improving, but they are still showing results in stability tests. Dig to have a look at the interface and how it is behaving with the new load.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze

    This layer can possibly wake up with large triggers. Avalanches & cornices hitting the slopes are both potential triggers.

  • Storm Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely - Very Likely

    These are on all aspects, and have different characteristics. Some slabs are settlement slabs, wind pressed slabs and wind loading slabs. These are expected to be a short term problem.

Avalanche Summary

No new avalanches

Snowpack Summary

We have yet another crust from yesterday's heat. It is thin and apparent up to 1900m. It may be higher on solar aspects. At the moment, new snow from last night has the crust down 5 cm's at valley bottom. Yesterday saw up to 14cm's of snow near the divide and 5-7 closer to the road. At treeline and above, this relatively warm snow was blown into new storm slabs. These slabs appear quite suddenly in open, exposed terrain. Expect to find them near 2100m. The buried wind slabs below are starting to heal up reasonably well, but we have seen a failure down 30cm's in some areas. Cornices are forming rapidly and should be treated with caution. Mud lake snow depth is 112cm and Burstall Pass is 159cm's.
