In reply to ryan_d:
Yesterday I agree with the others that there wouldn't have been many cornices left.
However today cornices will be forming fast on E / NE / N aspect on the strong SW winds and heavy snow today. They will also be very unstable, being fresh sitting on an icy base.
Aonach Mor East Face is not a place I'd want to be for a good while after the forecast for the next few days, the majority of the routes can suffer cornice problems and the crag aprons are notorious avalanche hot spots. You'll really want another thaw or a good while for things to settle down before visiting there IMO, however there are some routes you can ab down and normally climb without cornice issues and lowering your avalanche risk, one of them is Morwind.

As another poster suggested the west face routes are a better bet when snow has been falling or has been redistributed on strong westerly winds, as the routes will be scoured out rather then piled up with wind slab and the avalanche / cornice risk is likely to be much lower.
