Avalanche Activity

SC 29.12 Moderately bonded snow in wind sheltered locations on W through N to E aspects above 800m. Avalanche Hazard Moderate

Forecast Snow Stability: Below 800 metres the snow will be generally well bonded and stable, firming up as the freezing level lowers. In wind sheltered locations on West through North to East aspects above 800 metres moderately bonded snow will be present. Worst affected areas will be around steep corrie rims, gully tops etc. The avalanche hazard will be Moderate.

Snowpack Structure

Forecast Weather Influences: Light overnight snowfall above 600 metres, followed by a mainly dry day with just a trace of snow. South-Westerly winds overnight, veering to become fresh North-Westerly during the day. 750 metre freezing level overnight, lowering to 450 metres by daybreak. Observed Weather Influences: Showery precipitation, heavy at times, turning to snow above 750 metres during the afternoon. Gale force South-Westerly winds. Freezing level around 850 metres. ObservedSnowStability: A fluctuating freezing level has encouraged consolidation with wet but relatively stable snow present below 800 metres. Between 800 metres and 1000 metres on West through North to East aspects areas of moderately bonded windslab are present in steeper wind sheltered locations. Localised moderately to weakly bonded windslab has formed in steeper wind sheltered locations on North to East aspects above 1000 metres. The avalanche hazard is Considerable.
