LO for 1/2/25. Unstable windslab mainly on N-E aspects above 1000m. Fragile cornices above these aspects. Moderate hazard.

Forecast Snow Stability: Unstable windslab will be deposited overnight, adding to existing accumulations mainly on North to East aspects above 1000 metres. There will also be more localised windslab deposits on North-Westerly aspects. Fragile cornices will be present above these aspects. On other aspects the snowpack is generally shallow with good stability. The avalanche hazard will be Moderate.

Forecast Weather Influences: A passing front will give overnight precipitation, falling as snow above 900 metres, followed by a dry day. Very strong Southerly winds initially ease and veer overnight to become fresh Westerlies during the day. The freezing level will be around 900 metres. Observed Weather Influences: It was a dry day with a fresh South-Westerly wind. The freezing level was around 1000 metres. ObservedSnowStability: Localised areas of moderately bonded windslab persist and gaining depth due to wind redistribution, mainly on North to East aspects above 1000 metres with gullies and corrie rims most affected. Fragile cornices are present, mainly above these aspects. Stability on other aspects is generally good. The avalanche hazard is Moderate.
