Forecast Snow Stability: Very cold air temperatures will maintain a slow rate of consolidation. Poor to weakly bonded windslab will persist in wind sheltered locations on East to South aspects above 900 metres. Fragile cornices will be present above these slopes. Moderately bonded snow will be encountered below this altitude and on North-East and South-West aspects. Exposed locations will be wind scoured and stable. The avalanche hazard will be Considerable.

Forecast Weather Influences: Mainly dry with just a trace of snow forecast. Moderate, occasionally strong, West-North-West veering North-West winds. Surface freezing level overnight, rising to 500 metres by mid-afternoon. Observed Weather Influences: Snow showers to glen level overnight and during the morning, followed by a mainly dry afternoon. Strong North-North-Westerly winds. Freezing level around 400 metres. ObservedSnowStability: New snowfall and persistent drifting have rapidly formed unstable windslab in wind sheltered locations on mainly East to South aspects above 900 metres with fragile cornices forming. Shallower, moderately bonded accumulations present below 800 metres. Some cross-loading on North-East and South-West aspects. Exposed slopes are becoming scoured and stable. The avalanche hazard is Considerable.
