Wind slab
- Above 800 m
Forecast Snow Stability: New snow and wind transport of existing snow will form unstable windslab in wind sheltered areas, most affected will be sheltered gullies and slopes with a North-West through North to Easterly aspect mainly above 800 metres. Fragile cornices may form in similar locations. The existing snowpack will be generally stable with a firm, icy surface developing in places. The avalanche hazard will be Considerable.
Forecast Weather Influences: There will be a return to colder conditions with a freezing level through the day of around 600 metres. New snow and fresh to strong variable South-Westerly winds will affect the area overnight and through the course of Friday. Observed Weather Influences: Milder conditions overnight gave a period of rain with sleet on the higher slopes. Winds have been strong to gale force generally South-Westerly. The freezing level initially this morning was above the summits but had lowered to around 900 metres by mid day. Light snow showers are expected through Thursday afternoon. ObservedSnowStability: Surface snow instabilities exist on the steepest slopes and gullies mainly above 1000 metres, these are in the main avoidable, elsewhere the snowpack is soft moist and generally stable. The avalanche hazard is Low.
