Avalanche Activity

Some fresh snowdrifts on east-facing slopes

Avalanche danger continues to be MODERATE. The snowstorm on Thursday led to a rise in the frequency of danger zones. They occur near ridgelines on east-facing slopes where there is fresh snowdrift. On north-facing slopes at high altitudes, there is a persistent weak layer. Slabs are possible with large additional loading on N/E facing slopes: small to medium sized avalanches.

Snowpack Structure

Snowdrift accumulations have been deposited on south-facing slopes atop a hardened old snowpack surface above the treeline. On north-facing slopes the old snowpack is unfavourably layered.

Weather Synopsis

Summit zones will be shrouded all day long in heavy cloud, light snowfall is expected in Upper Styria. Winds will be strong, especially in the afternoon at high altitudes. At 2000 m: -13 degrees, with the windchill added it seems far colder. Little change in weather conditions is expected: heavy cloud, intermittent snowfall in Upper Styria. Strong winds from the northwest. The southern mountain massifs will probably remain dry.

Tendency

It will remain cold. Little change in avalanche danger levels.
