I live in Fort William and i am confident that we will see the first noticeable but brief snowfall of the Autumn on Nevis Range. Mountain snow fall in September is not particularly unusual but 'lasting' snows until the following winter are exceptionally rare in September such as the falls that occurred at the Cairngorm mountains in early Sept 76 following the famously hot summer that year ,particularly south of the border. Keep your eyes on the Aonach Mor webcams on Tue for a dusting near the summit.
