Another negative here. I know there has been some fresh snow in the last few days, but when we were up that way last Thursday, Friday, Saturday the cover was very patchy - great skiing in north and northeast facing corries, with a few runs down to 700m or so, but nothing of any significance on many hills, nothing at all on south facing slopes, so I don't think 10cm or so of fresh snow will fill things in enough. Ben Alder plateau did look very white but.
