Another warm day with plus six degrees Celsius recorded on the summit of Cairngorm. The snowpack remains consolidated and stable throughout.
Below 900 metres the snowpack is patchy and depleting rapidly, and will continue to do so in the mild temperatures. Drooping cornices remain around some corrie rims, and in some cases there are glide cracks and fractures well back from the edge. These will be one of the main hazards over the next couple of days particularly if they get the direct sunlight in prospect for tomorrow.
Snow cover remains good at higher elevations, with excellent cover on the plateau. The spring “corn” snow makes for good travel on ski for those prepared to walk to the snow line.

The snowpack at the moment consists of melt freeze grains with some crusts. [The crystal screen here is inserted just to give a bit of definition]. It is all rather granular, and unremarkable.



The warm temperatures of recent days has resulted in flowing water in the corries. The lochans here in Coire an t-Sneachda are thawing, with pools of water visible.

Cornices in many places have gone, but even the remnants look a bit suspect in places.
