Forecast Snow Stability: A period of higher instability will occur overnight as mild and wet conditions affect all levels. Colder conditions by morning will start to re-freeze the older snowpack. Fresh unstable windslab will form in wind sheltered locations. Gully exits and steep scarp slopes with a mainly Northerly to South-Easterly aspect above 850 metres will be particularly affected. Fragile cornices may form above these areas. Avalanches are likely. The avalanche hazard will be Considerable.
Forecast Weather Influences: The freezing level will rise above the summits later on Sunday with rain affecting all levels overnight. It will become very windy. There will be a return to colder conditions by morning with the freezing level around 600 metres. Westerly gales with frequent and sometimes heavy snow showers will continue through Monday. Observed Weather Influences: The freezing level rose above the summits overnight with some rain affecting all levels. Cooler conditions returned today with the freezing level around 850 metres. New snow is affecting slopes above 750 metres. Winds have been strong to gale force generally South to South-Westerly. ObservedSnowStability: Areas of windslab are forming in wind sheltered locations mainly above 850 metres. Locations most affected are summit gullies and steep slopes with a generally North-West through North to Easterly aspect. Fragile cornices exist above these areas. The avalanche hazard is Considerable.
