Northern Cairngorms

Forecast Snow Stability: Unstable windslab will become deeper and more widespread on steep West to North-East aspects above 850 metres, where avalanches are likely. West through North to North-East aspects will also be affected by cross loading. Crag aprons, gullies and coire rims will be affected, with unstable windslab also presenting on steep banks, convexities and in burn lines at elevations above 500 metres. Cornices will present an ongoing threat of collapse. The avalanche hazard will be Considerable.

Forecast Weather Influences: The passage of Storm Chandra will bring continual snowfall above 500 metres on storm force South-Easterly winds. The freezing level will mostly remain between 600 and 700 metres. Observed Weather Influences: Snow fell for much of the forecast period, from 500 metres upwards. Winds were predominately from the South-East and gale force. The freezing level was around 650 metres. ObservedSnowStability: Unstable windslab is present on West through North to North-East aspects above 850 metres. Steep wind sheltered locations are mostly affected such as coire rims, gully tops and crag aprons. At lower elevations between 700 metres and 850 metres, localised moderately bonded windslab was deposited becoming deeper as the day progressed. Terrain features such as steep rollovers, convexities and steep banks are mostly affected. The avalanche hazard is Considerable.
