Wind slab
- Above 900 m
Forecast Snow Stability: Unstable windslab will continue to develop gaining depth and becoming more widespread in wind sheltered locations. North-West through North to East aspects above 900 metres will be most affected particularly in gullies, scarp slopes and steep coire rims. Cross loading may affected other sheltered aspects. Fragile cornices will exist above these aspects. Wind exposed slopes will be scoured, icy with better stability. The avalanche hazard will be Considerable.
Forecast Weather Influences: The freezing level will be around 500 metres until dawn then it will slowly rise ending up above the summits by the end of the day. Snow showers overnight Sunday then dry through Monday. The very strong Westerly winds will ease briefly then strengthen becoming fresh to strong South-South- Easterly. Observed Weather Influences: After storm Dave passed through it left very wintry conditions. It was a wild day on the hill today with very strong Westerly winds with unexpected stronger gusts. lots of drifting snow on to Easterly aspects. The freezing level was around 550 metres. ObservedSnowStability: Unstable windslab exists and was becoming more widespread through the day. Greatest accumulations are in wind sheltered areas mainly above 900 metres particularly in sheltered gullies and on steep slopes with a NW, N, NE, E and SE aspect. Fragile cornices exist above similar aspects. Cross loading may affect other wind sheltered locations. Wind exposed slopes are firm and often icy with better stability. The avalanche hazard is Considerable.
