Forecast Snow Stability: Unstable windslab will become more widespread on Easterly to Southerly aspects above 900 metres. North to North-East facing slopes will be affected due to cross loading. Steep wind sheltered locations such as coire rims and gully tops will be most affected particularly where accumulations develop over the old snow. Fragile cornices will continue to develop throughout the period. The avalanche hazard will be Moderate.
Forecast Weather Influences: Snowfall throughout the forecast period, this is expected to be heaviest during the day. Gale force North-West winds will ease a little during the day. Very cold conditions; freezing at glen levels. Observed Weather Influences: A cold day with frequent snow showers on gale force North-Westerly winds. The freezing level at midday was around 600 metres. ObservedSnowStability: New accumulations of unstable windslab have developed on East to South aspects above 900 metres. North to North-East aspects are also affected by cross loading. The greatest instability is where accumulations have achieved depth in wind sheltered areas, such as coire rims, gully exits and crag aprons. Fragile cornices have also developed. The avalanche hazard is Moderate.
