Italy - Aosta Valley, etc.
Aosta Valley wrote:The danger level is 5-very strong in Gran Paradiso valleys, central and upper part of Lys and Ayas, Valtournenche valleys, 4-strong throughout the remaining regional territory.
The avalanches problems are the fresh snow and the wind-drifted snow:
the snowfalls continue and intensify on Monday afternoon and in the night between Monday and Tuesday, when the spontaneous avalanche activity will be more intense and widespread throughout the region. The situation is more critical especially in the south and east of the region, where the amount of fresh snow at the end of the episode can exceed two meters above 2100-2300 m where great avalanches are likely.
