Considerable avalanche danger in high altitudes due to snowdrift! During the day the warning can cause spontaneous avalanches!
Considerable avalanche danger above 1.400 m AMSL! In low altitudes the avalanche danger scale stays low. Fresh drift snow deposits are dangerous in the eastern sector adjacent to ridgelines as well as in slopes. Low additional loads can trigger Medion slab avalanches. During the day spontaneous avalanches can occur due to warming. Their sizes are medium in high altitudes but low in low altitudes.
The snow base is in general compact only in high shady slopes the base is composed of faceted snow. During Saturday evening drift snow layer have formed which are not yet efficiently bonded with the snow base. Sunday night additional drift snow in the eastern sector is called (prognosis models differ significantly). Weak layers within the snowdrift as well as to the snow base are to expect. Strong warming and rain up to high high altitudes can lead to destabilization.
Sunday night till Monday noon heavy snowfall is predicted in the northern region. Due to forecast uncertainty the amount of new snow is unsure but may be between 10 and 50 cm. Strong to stormy winds from northwest are called.temperatures are rapidly increasing during the day, precipitation can occur as rain even in high altitudes. From noon on precipitations are stopping, clear skies are possible. Temperatures in the western part of the northern region +1 degrees in the eastern part up to +5 degrees.
Tuesday will be unusually warm, Wind slab problems and avalanche danger are decreasing.
