Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely - Very Likely
    Größe
    1.5–2.5
    Found at treeline and above up to 50cm thick. They are being found on all aspects due to reverse loading patterns of recent winds.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    2–3.5
    Widepsread avalanche activity observed recently stepping down to the persistent deep layers such as Jan 6th Surface hoar and the Dec 15th Facet surface hoar interface. Any human triggerred slides will also likely step down to this interface

Weather Forecast

Monday is to bring sunny skies with cloudy periods. Alpine temperature is forecast to be -7c with west winds of 25km/h.

Avalanche Summary

Two new avalanches were observed within the last 24 hours: The Tent Bowl had one size 3 that ran to the bench with a crown depth up to 150cm. On the bed surface, you could see that the avalanche stepped down in many places.A second new avalanche size 2.5 was observed over Parallel Falls which ripped a slab of 80cm thick along the base of the falls.

Snowpack Summary

The alpine has a variety of wind effect that goes into tree line. This wind effect is on all aspects. Natural activity has slowed down but conditions still look primed for human triggering. Any avalanche that is triggered has a high likelihood to step down to the persistent deep layers. These layers include the Jan 18th and 6th surface hoar layers down being found below 2400m down around 1m+ and the Dec15th facet interface down 150cm being found all the way up and into the alpine. Stick to conservative terrain and minimize your exposure to overhead areas.
