Avalanche Activity

Considerable danger: wet-snow/glide-snow avalanches, and small fresh high-altitude snowdrifts

Up to high altitudes, 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

At high altitudes, up to 10-15 cm of fresh snowfall was registered, in exposed terrain transported, and generating fresh snowdrift accumulations which are increasingly trigger-prone with ascending altitude. The snowpack is mostly compact and stable, weakened by rain impact at low altitudes, wet down to the ground. 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.
