A change of wind direction has caused redistribution of the existing soft snow to leave areas of unstable windslab in sheltered locations. Complex mountain terrain can cause local winds to be significantly different from the forecast wind so these sheltered locations might not be where you’d expect them to be. The North face of Ben Nevis is often affected like this.
Two human triggered avalanches on Aonach Mor and reports of more on Ben Nevis. Several teams either turned back or changed their plans after finding unstable snow.
