Avalanche Activity

NC 11.01 Avalanches likely on NW through N to E aspects above 950m, more localised below 950m. Cornices! Considerable Hazard.

Forecast Snow Stability: Fresh deposits of poorly bonded windslab will develop on North-West through North to Easterly aspects above 950 meters. Areas particularly affected will be gully tops, corrie rims, crag aprons and the leeward side of ridge crests, where avalanches are likely. Cornices will continue to build on these aspects. Below 950 meters, on the same aspects, localised windslab will develop in wind sheltered locations, such as shallow gullies and steep banks. The avalanche hazard will be Considerable.

Snowpack Structure

Forecast Weather Influences: Storm force West-South-West winds easing slightly to gale force and backing to become South-Westerly. Frequent snow showers throughout the forecast period. The freezing level will be around 700 meters. Observed Weather Influences: Gale force South-South-East winds. Frequent showers falling as snow above 600 meters. The midday freezing level was around 800 metres. ObservedSnowStability: Localised accumulations of unstable windslab has developed on North-West to North-East aspects above 900 meters. West and East aspects are also affected due to cross loading. Areas most affected are gully tops, corrie rims, and high, wind sheltered locations. On other aspects and at lower elevations the snowpack is generally scoured and stable. The avalanche hazard is Moderate.
