In sintesi

Although the snowpack continues to strengthen, it is possible to trigger large avalanches from shallow areas.

Problemi valanghivi

    These deep persistent slabs at tree line and sheltered alpine slopes may be triggered from shallow areas within the snowpack.

Weather Forecast

Total snowfall amount of 10cm is expected over the next few days, with light winds and seasonal temperatures.

Snowpack Summary

Surface Hoar continues to form. A strong mid-pack overlies approximately 20-40cm of facets. Isolated wind slabs still exist in open areas at tree line and alpine elevations. The interface between the mid-pack and facets is most susceptible to human triggering from shallow areas.

Avalanche Summary

Limited observations today. There is past evidence of large deep slides in wind loaded features that released in the last cycle.

Confidence

Intensity of incoming weather systems is uncertain on Saturday
