GC 29/12 Weakly bonded windslab mainly on steep, sheltered N to E aspects mostly above 850m. Cornices fragile. Av haz Considerable.

Forecast Snow Stability: Overnight, and during the early morning weakly bonded windslab will continue develop in steep wind sheltered locations. North to East aspects above 850 metres will be mostly affected but some other sheltered locations may also have poorly bonded deposits due to cross loading. Steep coire rims and sheltered gullies will be particularly affected. Cornices will be fragile and prone to collapse. The avalanche hazard will be Considerable.

Forecast Weather Influences: Showers quite frequent during this evening and overnight falling as snow mainly above 900 metres with strong South-Westerly winds. Drier for Friday, winds easing becoming North-Westerly then Westerly the freezing level lowering to around 500 metres. Observed Weather Influences: Precipitation fell mostly as rain below 850 metres, this has thawed a lot of yesterday\'s lower lying snow. The freezing level was around 900 metres with the midday summit temperature of minus point five degrees celsius. The winds were strong to gale from a South-Westerly direction. ObservedSnowStability: Deposits of windslab have continued to develop through today, these are poorly bonded particularly where they have achieved depth in sheltered gullies, steep slopes and coire rims with a North to Easterly aspect above 850 metres. Cornices are fragile and difficult to spot in the poor visibility. The avalanche hazard is Moderate.
