Forecast Snow Stability: Initially, overnight high freezing levels, strong winds and driving rain will saturate the existing snowpack leading to wet snow instabilities on all steep slopes. Then the snowpack stabilising as the freezing level falls again. Deposits of new windslab forming during the morning on NW through N to E aspects above 900 metres these are not expected to be deep or extensive. Most affected locations will be gully tops and steep coire rims above 900 metres. The avalanche hazard will be Low.
Forecast Weather Influences: Overnight Wednesday the freezing level will be well above the summits with rain at all levels accompanied by strong the gale force East-South-Easterly winds. Late morning the freezing level lowing to around 900 metres with light snow showers. Winds remain stong to gale force East-South-Easterlies. Observed Weather Influences: Overnight and the freezing level briefly rose above the summits followed by a fall in temperatures and some very light snow above 850 metres. Cloudy and misty with some further light snow fall this morning then a mainly dry day with the freezing level at around 950 metres. Winds were light South-Easterly. A slow thaw is diminishing the snow cover at lower levels but some icy footpaths and hillsides still persist. ObservedSnowStability: Last night above 850 metres the snowpack under went a brief a thaw freeze cycle producing a surface crust it continues to consolidate and is generally stable. Localised, shallow accumulations of new windslab was developing mostly on North-West through North to Easterly aspects above 950 metres these are not deep or extensive and avoidable. Most affected locations are gully tops and steep coire rims above 950 metres. The avalanche hazard is Low.
