Avalanche Activity

LO for 27/1/24. Hazard mainly on N-E-SE aspects; windslab above 1050m and wet snow below. Fragile cornices. Considerable hazard.

Forecast Snow Stability: Fresh unstable windslab will continue to accumulate with greatest deposits on North through East to South-East aspects above 1050 metres. There will be wet snow instabilities on the same aspects at lower elevations mainly in the evening and overnight with some consolidation here during the day. Aspects exposed to the wind will be generally stable. Cornices will be fragile and prone to collapse. The avalanche hazard will be Considerable.

Snowpack Structure

Forecast Weather Influences: Gale force South-Westerly winds will ease slightly through the day. Showers will fall as snow above 1050 metres. The freezing level will be around 1150 metres. Observed Weather Influences: Gale force South-Westerly winds and snow showers. The freezing level was slowly rising and around 650 metres at midday. ObservedSnowStability: Fresh unstable windslab is present mainly on North through East to South-East aspects above 800 metres. Fragile cornices were developing above these aspects. The older snowpack is generally stable, firm where exposed to the wind. The avalanche hazard is Considerable.
