A quick update following the bad weather this week.
Snow has settled down to 2300/2500m but this will quickly disappear below 3000m with the sun.
Above this, there is 15cms of fresh snow at the Torino hut and 20cms at the Cosmiques hut, (40cms of windblown snow throughout the week), 30cms of windblown snow at the Gouter hut and 20cm at the Envers hut. (see photo).
Since the beginning of the week, at lot more snow has probably fallen above 3800m and the snow cover will have been affected by the strong winds. This will have created an avalanche risk, notably on the 3 Monts route, for which it would be wise to wait a bit.
After the bad weather, the mixed routes look white again but the conditions are unlikely to have improved. However, the temperatures have dropped and, if this continues there should be a, temporary, improvement in the general conditions at altitude.
Concerning the rock routes, it is necessary to wait a bit for the rocks to dry.
