In reply to rodw:
Ledge Route is gained from Number 5 gully which funnels snow from a huge avalanche prone bowl above (with slopes from east through north to west). I personally wouldn't be anywhere near it until the conditions stabilise a bit. Please take care as we have already lost too many in avalanches this year.
From SAIS (the cold conditions means things will only improve slowly):
Forecast Snow Stability & Avalanche Hazard
Large areas of moderately bonded snow will be present, mainly on North, North-East, East and South-East aspects above 800m. Additionally, localised areas of unstable windslab will be present on some steeper slopes of the same aspect. Where old snow is exposed, it will be frozen and stable. Remaining cornice will be unstable. The avalanche hazard will be Considerable
Forecast Weather Influences
It will remain cold and dry with light winds from an East or North-Easterly direction.
