A cold, dry, part cloudy day. A strengthening East to South-East wind is redistributing loose snow onto sheltered locations at all elevations, where new windslab is forming mainly on South-West to North aspects, most notably, on steep slopes at higher elevations.

(Above) Windward aspects in the Fannaichs. Accumulations of windslab can be found on what would normally be considered to be wind exposed terrain, but which is affected due to cross loading.

(Above) Drifting snow (spindrift) close to the ground at moderate wind speeds, but as the wind strengthens, more snow is eroded on windward terrain and is blown higher above ground level. New windslab can build at an alarming rate in sheltered locations during times of heavy snow redistribution.
