Glide-snow and (as day unfolds) wet-snow avalanches on sunny slopes

Glide-snow and (as day unfolds) wet-snow avalanches on sunny slopes

Below 2200m in all aspects medium-sized (isolated large-sized) glide-snow avalanches are possible. Caution on slopes with glide cracks. Due to solar radiation and daytime warming, wet slides and avalanches can release on sunny slopes in particular.

The snowpack shows the effects of rain and wind from the last few days. Up to 2200m it is thoroughly wet, up to 2500m it is moist. During nights of clear skies, a melt-freeze crust forms below 2500m which is capable of bearing loads. The rain and mild temperatures have helped the snowpack to quickly settle. Due to the dryness of the air, the snowpack surface softens little on sunny slopes, in the other aspects it remains hard and dry, thus reducing avalanche activity to a minimum.

A high-pressure front determines weather conditions today. The sub-tropical air remains dry and warm, sunshine all day long. At the edge of this front, the NW wind will be stronger than it was yesterday, but will soon slacken off. Temperature at 2000 m: +9 degrees! Brisk to strong NW winds at high altitude, easing later on.

Following a night of clear skies, Sunday will be mild and partly sunny. Avalanche danger is subject to a slight daytime cycle.
