Avalanche Activity

Considerable danger: wet-snow/glide-snow avalanches

Increased loose-snow and wet-snow avalanches possible during the course of the day due to wetness, radiation and warmth. Glide-snow avalanches can trigger at any time of day or night and grow to larger size. Danger zones occur near ridges, behind discontinuities and in wind-loaded gullies and bowls, esp. on steep shady slopes the older drifts are often trigger-prone. Small-to-medium slab avalanches and also loose-snow avalanches can be triggered by large additional loading. In high alpine regioins the danger zones are more frequent.

Snowpack Structure

The old snowpack is significantly weakened due to rain impact, it is wet down to the ground. This reinforces gliding movements. At higher altitudes there was 10-15 cm of fresh snow registered. In ridgeline terrain and exposed zones there was snow transport and small drifts were generated, these are increasingly prone to triggering with ascending altitude. Below 1500 m there is little snow on the ground.

Weather Forecast

Tuesday daytime: Residual clouds and fog will disperse, pleasant conditions with sunshine, cirrus clouds and some convective cloud build-up in afternoon At 2000 m:-2 to +4 degrees. Light W/NW winds.

Tendency

On Wednesday, tranquil weather, lots of sunshine, mild. Danger of dry-snow avalanches will recede further. Danger of wet-snow avalanches will increase during the course of the day. Main problem: wet-snow and glide-snow avalanches, possible often.
