Kernpunkte

Just when you think it should start to warm up, it just gets colder. Decent skiing will most likely be found just below treeline to valley bottom.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    Wind slabs are everywhere. In most areas they are resting on a thick layer of facets and could be easily triggered in unsupported terrain.
  • Loose Dry

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–1.5
    Any new snow will come in cold and light. It could build momentum and start to entrain the surface facets. Steep gullies will be suspect.
  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely
    Größe
    1.5–3
    This problem is a "low probability, high consequence" situation. While difficult to trigger, if the layer does fail it will result in a full depth avalanche.

Weather Forecast

On odd thing to write in March, but expect another cold snap. Friday night/saturday morning's low could be s low as -32 on the Spray Rd!! To make it even stranger, we are expecting a bit of snow as the temperature falls. Not much, but about 5cm is expected. Calm winds throughout the week end.

Avalanche Summary

Nothing reported today.

Snowpack Summary

We continue to loose strength in our entire snowpack. All elevations and aspects have felt the effects of the cold. In alpine and treeline areas this has helped to a certain degree. Slabs have been weakened and are becoming less "triggerable". Yet, at the same time, the same faceting process is making those thick/thin transitional areas more sensitive. It's an interesting balance, one that is shifting daily. We've seen some large, full depth avalanches lately that are giving us hints towards the slow, but steady change in the alpine. Treeline and below are more straight forward. The snowpack has basically lost it's entire structure.
