Little outgoing longwave radiation overnight, wet snow is the main danger.

Little outgoing longwave radiation overnight, wet snow is the main danger.

The avalanche risk is moderate below 2800 m and low above that. In a few places in the terrain, wet avalanches can still be triggered by winter sports, in particular in very steep terrain below around 2800 m where there is still snow on the ground. With the rain, the triggering of wet avalanches below around 2400 m increases slightly during the day. In wet snow, avalanches can tear through to the ground, reach medium size and, if the terrain is unfavourable, advance into the green.

Above around 2400 m, there are isolated avalanche prone locations in the extended northern sector where medium-sized slab avalanches can be triggered in the persistent weak layer. Be careful at the steep transitions from little to more snow. In addition, with a little new fallen snow and wind, small, easily recognisable snowdrift accumulations develop, in particular in high alpine regions, which can be prone to triggering in isolated cases. The main thing to watch out for here is the risk of being swept away and falling.

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 that is characterised by rain up to high altitudes, with the precipitation further moistening the snowpack during the daytime changes. On shady slopes above around 2400 metres, there are still weak layers of angular forms and deep rime in the old snowpack close to the ground. Low altitudes and sunny slopes at medium altitudes are snowed out.

Dense high and at times medium-high cloud fields will pass through on Tuesday night. On Tuesday, visibility is still clear in the morning, but the light is diffuse. However, the clouds will soon thicken and visibility will deteriorate. Rain showers are to be expected from midday. 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.
