In reply to PaulW:
There are 3 pages of detailed coverage in today’s Corriere della Sera. This is truly grim. 6 known dead, 8 recovered injured, 2 gravely. The agonising discussion is what to do next. The collapse took huge volumes of rock, indeed it describes the total volume of the material as mostly this. There are clearly a number of people unaccounted for.
The Italian benchmark for Alpine temps is the level at which it is 0 degrees, The zero therm. It was above 4000 metres at the time.
In Aosta they have had huge afternoon storms one of which produced golf ball sized hail and the 4000m zero therm is forecast for the next 5 days.
