Good advice from Alan Kimber about the hazard posed by cornices on many Scottish peaks at the moment:

"Had an extensive chat with the person who went 300m when Number Four Gully cornice collapsed underneath him. He is an extremely experienced mountaineer. He was around three or four metres back from the edge and had seen from the side that the cornice was not undercut. The fracture happened at least a metre behind him and blocks the size of a garage slid down. At the moment my opinion is that no climbs beneath cornices should be attempted. People on the plateau may trigger a release, if you do not! Even though there was no overhang on the cornice, it is clear that a hidden weakness existed and has been produced by the continuous wintry storms over the last three months. Plenty of action all over the Minus and Orion faces, where no serious cornice risk exists. I'd advise avoiding anything at the top of Observatory Gully, including around Hadrian's Wall for the time being. Better safe than sorry. The climber is okay with a broken lower leg."
