Poor visibility, crust and icy paths
24th February 2023
The Cairngorms were engulfed in cloud all day, making navigation challenging in the poor visibility.
Overnight, there had been a brief period with the freezing level just above the summits. The freezing level then fell sharply, with the snow surface becoming become firm in most locations. In places this was a thin crust, that varied as to whether it supported the weight of a person or not (travelling on foot).
There are isolated deposits of windslab on South-East to South-West aspects above 1000m. These are mostly shallow and avoidable.
With high pressure set to continue, the snowpack will be mostly firm and icy, with potential for serious consequences in event of a slip or a fall. Run outs are hazardous with many exposed rocks.
