In reply to Flinticus:
Different area, but from what I saw on Ben Lawers yesterday I'd agree with what Mark says. Did a figure-of-eight thing involving crossing the north side of Lawers to get at An Stuc, then coming back over the main summit via its north ridge. Quite large patches above 1050m on the north side and some awkward elongated strips below that. I didn't take an axe or even a pole, and was OK to sneak through various gaps and cross easy-angled patches, but it was a bit borderline in places. The snow itself was soft but had a fringe of brittle half-melted icy stuff that made it awkward to get on to the steeper patches. Beinn Ghlas at the start and Meall Corranaich at the end were both fine - scarcely stepped in any snow on either of those.
I'd imagine that the big Lochaber hills would be similar, and anything north- or east-facing high up would merit an axe on the sack even if you don't end up using it. The Glen Nevis side will be much less snowy but there's no harm in taking an axe just in case. Having said that, it is pretty warm again today and stuff will be coming off at a rate of knots.
