Rothenthurm

The old snowpack still contains various weak layers. In particular on wind-sheltered shady slopes, surface hoar is in some cases covered by snow. Deeper in the snowpack there are faceted layers, which in isolated cases are still prone to triggering, especially on seldom-used slopes with little snow cover. As daytime temperatures rise and the surface starts to moisten, in some places even the likelihood of dry avalanches being triggered is increasing during the course of each day.

Moreover, all regions can expect to see wet snow avalanches over the course of each day. Isolated wet slab avalanches may also be triggered by human activity. Gliding avalanches are to be expected mainly north of a line from the Rhône to the Rhine and also mostly tend to occur as the day progresses.

The night was often cloudy and there was some light precipitation, with the snowfall level lying at around 2000 to 2500 m. Daytime conditions were mostly sunny and mild.

Temperature

At midday at 2000 m, around +8 °C

Wind

Mostly light northwesterly, moderate at times in the afternoon

After clear nights, Wednesday and Thursday will be mostly sunny. Winds will be from northerly directions, mostly light on Wednesday and moderate at times on Thursday. Temperatures will remain very mild, with the zero degree level being at around 3000 to 3500 m.

The danger of dry avalanches will continue to decrease. The danger of wet and gliding avalanches will increase over the course of each day.
