NC for 1.12 Unstable windslab developing overnight on NW-NE aspects above 800m. improving later in the day. Hazard Moderate.

Forecast Snow Stability: As the winds increase overnight there will be a period of instability. Some light new snowfall and redistribution of existing snow will create unstable windslab, mainly on North-West to North Easterly aspects above 800 metres, with gully tops, coire headwalls and coire rims most affected. Cornices remaining unstable on the same aspects. Stability will generally improve as the freezing level drops later in the day. The avalanche hazard will be Moderate.

Forecast Weather Influences: Storm force Southerly winds overnight will ease, becoming fresh during the day. Rain, and summit snow, will clear east through the morning. Then mostly dry with bright spells in the afternoon, but the chance of the odd shower. The freezing level will rise above the summits overnight then fall to around 1000 metres during the day. Observed Weather Influences: Heavy snow showers fell overnight, accompanied by strong North-Westerly winds. Cloud during the morning dispersed to leave sunny conditions and light Northerly winds which backed South-Westerly during the day. The freezing level was around 300 metres. ObservedSnowStability: A widespread and mostly shallow accumulation of unconsolidated fresh snow has fallen on many aspects above 300 meters. Some isolated pockets of windslab are present in wind sheltered areas, mainly on southerly aspects above 800 metres. Elsewhere, stability is generally good. The avalanche hazard is Low.
