It felt roasting in Torridon today after the last few weeks of generally cold weather. Temperatures in the glen reached 8c but the light winds meant there was not as much melt as expected. There were only a few short periods where the higher tops appeared out of the cloud.
During the day we did see evidence of recent cornice collapse caused by the rapid rise in temperature.
The observations we take from the snow profile form only a part of our overall assessment of conditions. Today though a shovel test identified instability below the moist surface layers on a previously buried thin layer of graupel that was not immediately obvious. The graupel was still dry in the snowpack but melted almost instantly on the crystal card as the air temperature was plus 6.8c.
