Forecast Snow Stability: Unstable windslab will become more widespread and deeper as the day progresses. Avalanches are likely on steep East though South to South-West aspects above 800m. Below 800m and above 400m, localised windslab will develop on steep banks. North and North-East aspects will be subject to localised windslab due to cross-loading. Coire rims, headwalls, gullies, and convexities will be most affected. Fragile cornices will continue to develop. The avalanche hazard will be Considerable.

Forecast Weather Influences: Snowfall is expected throughout the period from glen level upwards. Winds will be very strong to gale force and generally North-Westerly. The freezing level will be at 400 metres during the day. Observed Weather Influences: Light snow showers overnight were followed by significant snow fall throughout the day above 200 metres. Winds were generally moderate and and from the North-North-West. The freezing level was around 400 metres. ObservedSnowStability: Unstable windslab accumulations built as the day progressed on South-East to South-West aspects above 950 metres. These were mostly in wind sheltered areas such as coire rims, headwalls, gully tops and convexities. On all other aspects and elevations there is a deep covering of light new snow, which is unstable in steep locations above 800 metres. Elsewhere, the snow cover is thinner and lies on bare ground. The avalanche hazard is Considerable.
