Forecast Snow Stability: Unstable windslab will continue to build throughout the forecast period, becoming more widespread, particularly on North-East through East to South aspects above 750 metres. Steep open slopes such as ridge flanks, coire backwalls and tops of gullies will be affected, where fragile cornices will continue to develop. Localised instabilities will affect other aspects and lower elevations. The avalanche hazard will be Considerable.
Forecast Weather Influences: Snow showers, with snow lying at all levels, will continue throughout the forecast period, more frequent overnight. There will be a persistent strong North-West to North airflow. It will remain cold with the freezing level barely rising above 300 metres. Observed Weather Influences: A day of frequent, occasionally heavy, snow showers with new snow at all elevations. Moderate to fresh West to North-West airflow. Cold, as the freezing level barely rose above 150 metres. ObservedSnowStability: There is a deep fresh snow cover on most aspects and elevations. Unstable windslab continues to build in wind sheltered locations, particularly affecting steep and very steep terrain on North-East to South-East aspects above 750 metres. New fragile cornice growth noted above similar locations. Some steep North and South aspects are also affected at higher elevations. The avalanche hazard is Considerable.
