Main danger: wet-snow avalanches

Avalanche danger is low in the morning and rises to moderate during the course of the day. On steep slopes with lots of snow and a smooth underground which have not yet discharged, glide-snow avalanches can trigger at any time of day or night in all aspects. Zones below glide cracks should be avoided. Due to daytime warming and solar radiation, wet loose-snow avalanches can trigger naturally, particularly on extremely steep slopes. Avalanches can grow to medium size and place exposed hiking trails at risk.

The snowpack was weakened over the last few days due to lack of nocturnal outgoing radiation, local rain showers and daytime warming. It is thoroughly wet widespread.

Wednesday will bring sunny weather amid harmless convective clouds in the afternoon. In exposed ridgeline and summit zones, northerly winds can be unpleasant. Temperature at 2000m: 8 degrees; at 3000m: +1 degree. Moderate to brisk northerly-to-northeasterly winds at high altitudes.

Over the next few days, a daytime rhythm of avalanche danger will set in.
