Forecast Snow Stability: Moderately bonded windslab will continue to develop on steep, mainly North-West to North-Easterly aspects above 850 metres. There may also be some cross-loading on steep sheltered West and East facing gully flanks and gully exits. Soft cornices forming above many of these locations. The avalanche hazard will be Moderate.
Forecast Weather Influences: The freezing level will be around 400 metres. Snow showers continuing overnight and through the day. Winds will be Moderate to fresh from a South-Westerly direction. Observed Weather Influences: Overnight, light snow showers fell to all levels, intensifying during the course the morning, then later in the afternoon becoming more sporadic.
