Wind slab
- Above 900 m
Forecast Snow Stability: Overnight, poorly bonded windslab will continue to develop on North-East to South-East aspects, this will be most widespread above 900 metres. Below this altitude instabilities will be localised on steep banks and burn lines. During the day, some light drifting is expected with localised unstable windslab developing around coire rims and gully exits on North-West to North-East aspects above 1000 metres. Cornices will be fragile. The avalanche hazard will be Considerable.
Forecast Weather Influences: Light snowfall is expected to clear during the night. Strong to gale force Westerly winds will ease to fresh during the day and back to become Southerly in direction. At dawn the 500 metre freezing level will steadily rise to around summit levels by the end of the day. Observed Weather Influences: A cold day with squally snow showers on strong to gale force Westerly winds. The freezing level at midday was around 600 metres. ObservedSnowStability: There was a period of snowpack instabilities during the night on North-West to North aspects above 950 metres. Unstable accumulations of windslab continue to build on North-East to South-East aspects above 950 metres. Localised windslab has developed on steep banks below. The greatest instability is around coire rims, ridge flanks steep rollovers and gully exits. Elsewhere the snowpack is covered by a thin crust. Recently formed cornices are fragile. The avalanche hazard is Considerable.
