In sintesi

Strong winds will probably make the alpine an unpleasant place to be on Thursday. Watch out for overhead exposure if you end up hiding out at treeline. Natural avalanches will become increasingly likely through the day.

    Avalanches are likely on steep, unsupported, or wind loaded features.  Watch for signs of instability like blowing snow, shooting cracks or natural avalanche activity.

Confidence

Moderate - Timing of incoming weather systems is uncertain on Friday

Weather Forecast

THURSDAY: 10-20cm of new snow overnight with another 5-15cm through the day, moderate to strong southwest winds, 1500m freezing level. FRIDAY: heavy snow with accumulations of up to 25cm, strong southerly winds, 1800m freezing level. SATURDAY: Heavy snow continues, strong south winds,  1700m freezing level

Avalanche Summary

Natural and artificially triggered avalanche activity was reported from across the region on Wednesday.  Cornices remain large and fragile and would likely collapse under the weight of a person.

Snowpack Summary

Between 40 and 80cm of new snow and strong winds have formed reactive soft slabs in steep, open, and unsupported alpine and treeline features. The upper snowpack sits on a widespread crust on all but high elevation north facing slopes. Cornices are large and weak.  The mid-pack is generally well settled.
