(nda) There is a great danger of avalanche on Christmas Eve in localities above 2200 meters, in an area of the Diablerets in the Vaudois Alps , across the Aletsch region and the Uri Alps up to the Pizol Range in eastern Switzerland, as the SLF wrote Sunday night. The level 4 avalanche danger also prevails in Nordbünden and Lower Engadine.
According to the SLF, spontaneous avalanches are expected in these areas and even large avalanches are possible. Below 2200 meters altitude, avalanches could be swept by the snow and get into the green, warns the institute. Suspended parts of taxiways are partially under threat.
People may be at the origin of avalanches
For snow sports off the beaten path, these conditions are dangerous, according to the SLF. People could already trigger an avalanche – ski tours, variations or snowshoeing are appropriate.
You must expect an altitude of less than 2400 meters because of the rain with wet and slippery snow avalanches. Between 2000 and 2400 meters, some of these snow slides can be big. In other regions of the Alps, the danger of avalanche is considerable. This corresponds to the middle of the five levels of alert.
