Some information about the recent snowfalls, which have reached as low as 2500m:

40 cm at the Goûter hut.

About 30/40 cm of windblown snow at the Col Flambeau, near the Torino hut.

40 cm at the Cosmiques hut.

All the Chamonix Aiguilles are plastered, (including next to the Envers des Aiguilles hut.)

20 cm at the top of the Grands-Montets.

There has been a lot of wind which will affect these estimations.  There will almost certainly be some deep snow drifts.  The strong winds are due to continue for a few more days at altitude.  It is necessary to wait until the snow cover stabilises and the rocks dry.  In the meantime, one needs to remain patient, choosing alternative, lower altitude routes.
