Stability: fair · Frequency: few
Only in shady high altitude slopes a snow cover is existing. Exposed areas are blown-off and bare or icy. In gullies and bowls the old snow cover ist weakened due to faceted snow crystals . Due to precipitation and warmth the snow surface gets moist and looses strength.
A low pressure system coming from Ireland crosses the eastern Alps results in a warm front. Dense clouds in the beginning and foggy on the norther side of the Alps with little precipitation. The snow line goes up to 2.000 m. In the afternoon skies are clearing but summits are only partially clear. In exposed areas vivid to strong southwesterly winds. Eventually stormy in Koralpe region. The temperatures are rising and will be around -2 degrees in the morning but 5 degrees in the afternoon in 2.000 m.
It stays mild and foehn-like. No significant changes of the avalanche danger situation.
Low avalanche danger, only little snow. Observe risk of falling.
Low Avalanche danger. A few danger spots due snow drift deposits in high altitude gullies and bowls and steep areas. Danger of being swept away and buried as well as risk of falling is to be considered. Small moist loose-snow avalanches coming from steep slopes are possible due to increasing warmth.
