Forecast Snow Stability: Fresh unstable windslab will progressively build as soft snow is redistributed, mainly on South to West aspects above 900m, where avalanches are likely. Areas most affected will be steep, convex terrain, such as coire rims and gully tops. Underlying weaknesses within the snowpack will persist on all aspects, with greatest instability on East to South aspects above 900m. Cornices will be fragile. The avalanche hazard will be Considerable.

Forecast Weather Influences: Another dry day is expected. It will be freezing at all levels overnight, rising to 400m during the day. Winds will be East-North-Easterly and steadily increase from light to strong throughout the forecasting period. Observed Weather Influences: A dry and sunny day, with light Northerly winds. It was freezing at all levels with a midday summit temperature of minus 9 degrees C. ObservedSnowStability: Instabilities within the snowpack persist on all aspects. The greatest instability is on steep Easterly to Southerly aspects above 900 metres especially around steep, convex terrain, such as coire rims and gully tops. Cornices are fragile. The avalanche hazard is Considerable.
