Avalanche Activity

GC29/12 New poorly bonded windslab forming mainly on N to E aspects above 850m. Other aspects, new snow instabilities. Moderate Haz

Forecast Snow Stability: The snowpack will consolidate further as rain affects all locations before rain turns to snow showers. Accumulations of new poorly bonded windslab will develop in wind sheltered locations. Areas most affected will be sheltered gullies, gully exits and steep corrie rims mainly on North to Easterly aspects above 850 metres. Other aspects will gain a new cover of snow and localised new snow instabilities may be present on many steep slopes above 850 metres. The avalanche hazard will be Moderate.

Snowpack Structure

Forecast Weather Influences: The freezing level will rise above the summits this evening for a short spell then fall to around 700 metres for the rest of the period. Initially showers falling as rain then snow mainly above 600 metres with strong South-West or Westerly winds. Observed Weather Influences: The freezing level fell during the morning to around 700 metres. It was a dry morning with some light showers falling as snow above 600 metres in the afternoon. The winds were fresh from the South-South-East. ObservedSnowStability: The overnight mild conditions and rain then a slight re-freeze have helped to consolidate the snowpack. A breakable surface crust is present on most aspects above 650 metres. Localised windslab deposits are still present mainly on North-West through North to Easterly asects above 950 metres with the tops of gullies and scarp slopes especially affected. The avalanche hazard is Moderate.
