Northern Cairngorms

Forecast Snow Stability: Unstable windslab will develop on South-East to South-West aspects above 900m. Widespread unstable windslab will remain on South-West through West to North aspects; more localised on North-East aspects. Coire headwalls, crag aprons and steep slopes especially affected. At lower elevations localised unstable windslab will be present on some steep banks and burn lines. Elsewhere above 1000m weaknesses will remain beneath a widespread friable crust. The avalanche hazard will be Considerable.

Forecast Weather Influences: Light snowfall is expected to clear by early morning. Fresh East-North-East winds will gradually back to become North-North-Westerly through the afternoon. The freezing level will be around 400 metres. Observed Weather Influences: Light snowfall cleared to leave a dry day with fresh Easterly winds. The midday freezing level was around 500 metres. ObservedSnowStability: Drifting snow at higher levels with unstable windslab developing on South-West, through West to North aspects above 900 metres. Cross loading has affected North-East aspects. Coire headwalls, crag aprons and steep convex terrain are most affected. At lower elevations localised instabilities are present on steep banks and burn lines. Elsewhere above 1000 metres weaknesses remain present beneath a widespread friable crust. Cornices are fragile. The avalanche hazard is Considerable.
