Amounts are not expected to be substantial and will mainly affect corrie rims and gully tops. Fragile cornices will start to build above these aspects. Windward aspects will become re-frozen and stable. The avalanche hazard will be Moderate.

Forecast Weather Influences: West-South-West winds overnight will remain strong throughout the period, backing South-Westerly during the morning. Rain will ease this evening, then light snow showers will continue throughout the period. Freezing level will drop sharply this evening and remain around 600m throughout the day.
