Forecast Snow Stability: Overnight moderately bonded windslab will develop in wind sheltered areas, continuing through the day. Greatest accumulations will be in sheltered gullies and on slopes with a mainly North-West through North to Easterly aspect mostly above 850 metres. Other aspects may be affected by cross loading. Fragile cornices will form in similar locations. Elsewhere the snowpack will generally remain stable, The avalanche hazard will be Moderate.
Forecast Weather Influences: The freezing level will lower to around 400 metres by dawn then slowly rise to be above the summits by the end of the day. Moderate to strong winds initially Westerly becoming all points Southerly. Precipitation all through the forecast period initially falling as snow mainly above 300 metres turning rain at lower levels as the freezing level climbs through the day.
