Considerable avalanche danger above the treeline - Wet-snow avalanches due to rain and warmth

At high altitudes the main problem is the fresh snow and freshly generated snowdrifts. Danger zones increase in size and frequency during the course of the day and with ascending altitude. One person can trigger a medium - sized avalanche. Activities in backcountry terrain demand experience in assessing avalanche risks on-site. In very steep rocky terrain, naturally triggered loose-snow avalanches, and in wind-loaded zones slab avalanches, are possible.

Due to warmth on Tuesday, a mild night with rainfall up to high altitudes, the snowpack is weakened. Fresh and older snowdrift accumulations increase in size and frequency with ascending altitude. Inside the drifts are weak layers, e.g. graupel. Fresh snow and drifts lie deposited atop a thoroughly wet and thereby weakened snowpack surface. At low altitudes the fresh snow of recent days fell on bare ground.

Nocturnal hours: after midnight precipitation will set in. At low altitudes below 1000-1500m from Lake Constance into the Vorderwald it will soon turn to rain. Wednesday: extensive cloud cover, rising temperatures. Below 1500m as of the morning hours, light rainfall, up to 2000 m in the afternoon. Visibility is often diffuse, foggy at high altitudes. At 2000 m: -1 to +2 degrees. Brisk to strong NW winds.
