Kernpunkte

A major warming on Wed and Thurs will likely trigger a significant spring avalanche cycle. Avoid avalanche terrain.

    Wahrscheinlichkeit
    Likely - Very Likely
    Größe

    High freezing levels over the next two days will lead to widespread wet avalanches, especially on solar aspects. Avoid avalanche terrain when the snowpack is moist or wet, and be very aware of overhead hazard.

    The basal facets are producing large slab avalanches that are failing on the basal facets.

Weather Forecast

Warm and mostly sunny conditions are expected for the next two days, before another wave of precipitation arrive on Friday. Freezing levels will reach 3300m on Wednesday and 3600m on Thursday with little to no overnight recovery.

Avalanche Summary

Several loose wet slides up to size 2.0 were triggered today by solar radiation on East, South and West aspects.

Snowpack Summary

Moist snow is found on all aspects and at all elevations except true North aspects above 2400m. The snowpack is turning isothermal at lower elevations. Isolated thin wind slabs are found at ridge crest in immediate lee slopes, but these have been unreactive to ski cutting. The basal facets and deoth hoar are reactive during times of intense solar radiation and/or warm daytime temperatures. Some recent avalanches have failed on the ground. Where cornices exist they are large and sagging.
