Avalanche Activity

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.

Snowpack Structure

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.
