Low avalanche danger, watch out for wet snow.

Low avalanche danger, watch out for wet snow.

The avalanche risk is low. With the rain, the triggering of wet avalanches increases slightly in the afternoon. This is in particular where there is still a lot of snow on the ground, i.e. mainly on very steep shady slopes at high altitudes and partly on east and west-facing slopes. The avalanches usually remain small, but can tear through to the ground in wet snow, occasionally reach medium size and, if the terrain is unfavourable, advance into the green.

The snowpack can only outgoing longwave radiation poorly overnight. No or only a very thin melt-freeze crust forms, which softens quickly in the morning. The snowpack underneath consists of compact snow characterised by rain. On shady slopes from around 2400 metres, there are weak layers of deep rime in the old snowpack close to the ground. The snowpack is moist to wet up to high altitudes. Low altitudes and sunny slopes at medium altitudes are covered in snow.

Dense high and at times medium-high cloud fields will pass through on Tuesday night. On Tuesday, visibility will still be clear in the morning, but the light will be diffuse. However, the clouds will soon thicken and visibility will deteriorate, with isolated rain showers during the day. Snow falls from around 2400 metres. The wind will blow weakly to moderately from different directions. At 2000 m around 5 degrees, at 3000 m around -2 degrees.

On Wednesday morning there will still be a lot of clouds and intermittent precipitation, then visibility will improve and the sun will come out. There is hardly any change in the avalanche risk.
