Northern Cairngorms

Forecast Snow Stability: Unstable windslab will continue to develop with avalanches likely on West through North to North-East aspects mainly above 900 metres. The greatest instability will be in steep locations such as coire headwalls, gullies, crag aprons and convex shaped terrain. Unstable cornices will overhang these aspects. Between 500 and 900 metres, more localised instabilities will be present on steep banks and burn lines. The avalanche hazard will be Considerable.

Forecast Weather Influences: Light snow showers throughout the forecast period. Gale force South-East winds will gradually ease to strong through the day. The freezing level will be around 700 to 800 metres. Observed Weather Influences: Snow showers on storm force South-East winds. The freezing level was at 500 metres. ObservedSnowStability: Significant drifting above 500 metres, with new accumulations of windslab developing above this altitude on West through North to North-East aspects. The greatest instability is above 900 metres in steep locations such as around corrie head walls, gullies and crag aprons and steep rollovers. Large cornices overhang these aspects. Between 500 and 900 metres, moderately bonded windslab has developed on steep banks and burn lines. The avalanche hazard is Considerable.
