Wind slab
- Above 850 m
Forecast Snow Stability: Unstable windslab will exist in wind sheltered locations mainly above 850 metres, Greater accumulations will be in sheltered gullies and on slopes with a mainly North through East to Southerly aspect. Fragile cornices may exist in these locations, other aspects may be affected by cross loading. Stability on windward slopes will be better with a firm possibly icy surface forming on the older snow. The avalanche hazard will be Considerable.
Forecast Weather Influences: New snow will affect the area mainly above 500 metres, winds will be Westerly strong to gale overnight veering West-North-West and decreasing fresh to strong through the day. The freezing level initially will be around 600 metres rising to 800 metres by evening. Observed Weather Influences: Heavy rain sleet and snow with strong to gale Westerly winds have affected the area. The freezing level rose this morning to around the highest tops with a lowering trend later to around 600 metres. Further snow showers heavy at times are expected through the afternoon. ObservedSnowStability: Unstable accumulations of windslab are forming in wind sheltered locations, greatest accumulations are in sheltered gullies and on North through East to South-Easterly aspects mainly above 850 metres. A return to colder conditions is aiding the consolidation process within the older wet snowpack. The avalanche hazard is Moderate.
