Forecast Snow Stability: The existing generally moist snowpack will continue to consolidate and will firm up through the day as the freezing level drops. Shallow accumulations of fresh unstable windslab will build overnight and throughout the day on mainly North through East to South-East aspects above 900 metres. Areas most affected will be coire rims and gully tops. Elsewhere any new snow will fall mostly on bare ground. The avalanche hazard will be Moderate.

Forecast Weather Influences: Strong South-Westerly winds will veer North-Westerly and decrease overnight, to become fresh to moderate. Frequent showers overnight, falling as snow above around 900 metres, will ease during the day and fall as snow to progressively lower levels. The freezing level will be around 900 metres initially and drop steadily to reach 400 metres by the end of the forecasting period. Observed Weather Influences: Strong South-Westerly winds. Frequent showers, mostly falling as snow above around 800 metres. The freezing level fluctuated between 800 and 1000 metres. ObservedSnowStability: The moist snowpack is generally consolidating. Some instabilities remain in deeper accumulations above 900 metres mostly on West through North to East aspects, particularly around coire rims and gully tops. Little snow remains below 600 metres. The avalanche hazard is Moderate.
