2nd January 2023
A dry and cold day on the hill today, with a penetrating moderate to fresh wind from the West-South-West. The visibility was excellent for the most part, with just some banks of cloud on windward up slopes.
The blanket of soft snow remains in sheltered locations such as on the coire floors, making for pleasant progress on ski and hard graft on foot. During the day some of this soft snow was redistributed creating windslab deposits in steep wind sheltered locations. Avalanche debris was observed from size one avalanches in Coire an Lochain, originating from either fragile cornices or additional loading close to the coire rim.
It is all change for tomorrow with increasing southerly winds expected to redistribute much of the soft snow and deposit new windslab on steep wind sheltered northerly aspects. Given the strength of the winds overnight and in the morning, soft snow is likely to drift as low as 600 metres and localised unstable windslab will be present on some steep banks and convexities.
Due to the passage of a front, the temperature will rise resulting in a slow thaw, and an associated period of instability when avalanches will be likely on North-West to North-East aspects above 900 metres.
