    Warm air temperatures and clear skies have produced spring-like conditions on steep solar aspects. Loose wet avalanches may begin small but could step down to deeper crust layers.

Avalanche Summary

Small loose wet avalanches were observed on steep south-facing slopes on Thursday.

Snowpack Summary

Warm air temperatures and clear skies have caused melting of the surface snow on south-facing slopes. Crusts may form overnight but should melt quickly in the mornings. The warm weather has settled the snowpack and may be improving the bond to the 30-50 cm deep rain crust from late November, but there are still limited observations of this layer. Lingering wind slabs may exist at higher elevations but are trending towards being unreactive. Cornices may be weakening with the warm air temperatures.
