In reply to joe.91:
For La grave, the last couple winters the bureau des guides have been issuing conditions updates (in french) complete with photos of each icefall. Don't remember what exact fb group they publish it on but if you email them you should get a response. Its not been massively cold in the alps yet but that is due to change tomorrow.
Update. Go to 'Guides La Grave' fb page.
