Lawinenprobleme

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    2–5
    Although the likelihood of a release is low, the consequences of a persistent slab release could be significant. These layers may wake-up with additional loading.

  • Storm Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Likely
    Größe
    1–4
    New snow and wind forecast for the next few days will add to a developing wind/storm slab problem. The sensitivity of this layer may be higher in some areas due to the possibility of underlying surface hoar.

Confidence

Fair - Intensity of incoming weather is uncertain

Snowpack Summary

Based on limited data streams, it appears as though the region received up to 15cm of new snow on Wednesday night. Relevant wind information has also been extremely limited; however, some data points suggest that winds were in the moderate (enough to transport snow) range. Forecast snow and increased wind values will add some more punch to this newly developing storm slab. This new slab sits over a variety of old surfaces which most likely include well settled storm snow from last week and surface hoar.There may be a thin buried surface hoar layer down about 95 cm. As well, the November rain crust now exists over 110cm down in some locations and may exist in combination with facets. These layers seems to have been unreactive in recent days, but may have the potential to 'wake-up' with additional loading.Average snow depths at treeline seem to be between 125cm and 150cm.
