Another calm and sunny day in the Northern Cairngorms, where suncream is arguably more important than a set of the latest waterproofs.
An interesting situation prevails at the moment with high pressure well established, resulting in inversions and mild temperatures at altitude. However, the snow surface has remained very cold possibly due to radiation cooling into the calm and clear atmosphere.
The important issue is that the snow surface has remained very hard and icy in many places even to low elevations. The consequences of a fall or slip cannot be over stated, particularly as the snowpack becomes more patchy low down. The exception to this is steep South facing slopes which are subject to direct sunlight. Here the snow has softened readily, giving some good skiing in some locations on ‘spring snow’.
That said, the burn lines and gullies are also rapidly being affected by glide cracks and fractures as the snow creeps down hill due to ductile flow. These holes and cracks present a hazard for the unwary, especially if they are lurking just over a convexity.
Little change is expected tomorrow.
