In reply to Oceanic:
A lot can change in 10 days or so, but Le tour ski slopes ( South facing) are still plastered with snow which may give you an indication of what to expect.
Forget neve unless your lucky or up extremely early or north facing, think at the very least a ice axe may be prudent.
Only back today so not 100% on the conditions you are likely to encounter, but a very unusual winter/spring.
A alternative game plan prior to leaving may be wise.
