Cornices are moderately sized and unstable. The avalanche hazard is Moderate.

Snow cover at around 850 metres with some small drifts in places.

Fresh to strong Westerly winds will slowly back to the South-West and ease slightly. Areas of unstable windslab will develop throughout the forecast period, affecting most wind sheltered locations, particularly on steep North-East to South-East aspects above 800 metres. Cross loading will affect other aspects, particularly around steep coire head walls and the tops of sheltered gullies. Unstable cornices will continue to develop. The avalanche hazard will be Moderate.
