Forecast Snow Stability: Accumulations of unstable windslab will continue to form in sheltered locations on mainly North-East through East to South aspects above 850 metres, where avalanches are likely. North and South-West aspects will also be affected due to variable wind directions. Cornices will be prone to collapse. Areas exposed to the wind will remain firm and icy. The avalanche hazard will be Considerable.
Forecast Weather Influences: Mainly dry overnight, except for a few isolated showers this evening. Throughout the day there will be regular snow showers. Moderate winds from variable North-Westerly directions overnight. Strong West-North-West winds during the day. The freezing level will remain below 200 metres throughout the period. Observed Weather Influences: A dry day with light to moderate North-Westerly winds, with stronger gusts at times. Feeling very cold with the freezing level remaining at lower levels, around 100 metres. ObservedSnowStability: Natural avalanche activity was witnessed on South-East, South, and North aspects. Widespread accumulations of unstable windslab are present in wind sheltered locations on mainly North-East through East to South aspects above 850 metres with more specific accumulations on North and South-West aspects and at lower altitudes. Greatest accumulations are around crags, buttresses, coire rims and gullies. Fragile cornices are also present. The avalanche hazard is Considerable.
