Northern Cairngorms

NC for 7.3 Unstable windslab + cornices, especially on E - S aspects above 800m where avalanches are likely. Considerable hazard

NC for 7.3 Unstable windslab + cornices, especially on E - S aspects above 800m where avalanches are likely. Considerable hazard

Forecast Snow Stability: Unstable windslab will continue to build and become more widespread, especially on East to South aspects above 800 metres, where avalanches are likely. Coire rims, gully tops, crag aprons, and ridge flanks most affected. Cross loading on to other aspects, mostly North-Easterly and South-Westerly. Localised windslab also on East to South aspects below 800 metres, particularly on steep banks and gullies. Fragile cornices will continue to develop. The avalanche hazard will be Considerable.

Forecast Weather Influences: Persistent and heavy snow showers overnight at all levels, becoming less frequent during the day. Very strong North-North-Westerly winds, backing North-West during the night. The freezing level will fluctuate around 100 metres. Observed Weather Influences: Snow showers, at times heavy. Gale force North-North-Westerly winds. Freezing level around 250 metres. ObservedSnowStability: Unstable windslab is building and becoming increasingly widespread, primarily on East to South aspects above 900 metres. Areas most affected are steep wind sheltered terrain such as coire rims, gully tops and ridge flanks. Cross loading on to other aspects. Localised windslab developing on East to South aspects below 900 metres. Fragile cornices are building above the same aspects. The avalanche hazard is Considerable.
