Fresh cornices forming. Strong SW winds with snow showers will form fresh windslab on sheltered NW through to NE aspects above 900 metres. Greatest accumulations will be on sheltered steep slopes, gullies and corrie headwalls. The snowpack will become increasingly unstable as temperatures rise, with snow turning to rain at lower levels. Wet snow instabilities will be present below 900 metres on many aspects.
Avalanches are likely.
Cornices prone to collapse. Fresh snow today from 700m. Thawing at all but the highest levels by Sunday. Strong winds remaining into Sunday. A strong mild South-Westerly airflow has brought heavy snow above 400 metres.
