Greatest accumulations will be on steep North-East, East and South-East aspects above 900 metres. This windslab will increase in distribution as the period progresses. The avalanche hazard will be Moderate.

Snowpack Structure

Forecast Weather Influences: The strong Westerly airflow will continue with frequent snow showers above 700 metres. Observed Weather Influences: After a mild and wet night, the freezing level has dropped to around 900 metres with snow showers. Storm force Westerly winds.
