Cracking day out

The snowfall continued for the duration of the day in the Northern Cairngorms. Although the snow was relatively light, the strong to gale force winds at higher elevations continue to transport it at pace. Wind sheltered (lee) slopes of a South-West to North-West aspect above 500 metres are achieving the greatest accumulations. North aspects also have accumulations due to cross loading.
Weaknesses persist in the existing snowpack and are being overloaded as more windslab develops. As such, a delicate avalanche situation prevails at relative low altitudes (especially above 500 metres). This was demonstrated again by the cracking windslab in the images below, which seams to be an almost daily occurrence at the moment.
Cracking windslab at approximately 550 metres on a North-West aspect. Indicative of weakness below the windslab.
Drifts in the trees at around 500 metres. Many of these features showed signs of weakness, with shooting cracks.
This tree demonstrates the continual snow transportation occurring at even low levels.
