GC.7/4 Moderately bonded windslab mainly on N to E aspects above 900m. Gullies affected. Cornices soft, fragile. Av Hazard Moderate.
Forecast Snow Stability: Further areas of moderately bonded windslab will continue develop in wind sheltered locations. North to Easterly aspects above 900 metres will be particularly affected with deepest accumulations in steep sheltered gullies, scarp slopes and coire headwalls. New snow deposits will also develop on all other aspects but these will mainly be lying on bare ground and are not expected to be extensive. New cornices will be fragile. The avalanche hazard will be Moderate.
Forecast Weather Influences: Overnight, the freezing level will lower to around 400 metres before rising to 700 metres during the day. Snow showers mainly above 400 metres and heaviest overnight, these will continue through the day and lessen. Fresh, Southerly winds will back, strengthen then decrease becoming North-North-Westerly. Observed Weather Influences: Overnight, the freezing level fell to around 800 metres with snow showers falling above 650 metres. During today the freezing level rose to around 930 metres with snow showers mainly above 850 metres, some sleet down to 650 metres. Winds were fresh to strong through the period mainly from a South-Westerly direction.
ObservedSnowStability: The old moist snowpack has consolidated. New shallow areas of moderately bonded windslab are building in wind sheltered locations mainly on North to Easterly aspects above 950 metres. These accumulations are generally localised, most affected areas are steep gully exits and coire headwalls. New cornices continue to develop above similar aspects. The avalanche hazard is Moderate.
