Abstract: The effects of climate change have largely affected all the nations of the European continent. In Italy, sudden and violent rainfalls have characterized the last summer seasons, while winter seasons have seen long periods without precipitation. Even in the Biellese Alps, located in the north-western part of Italy, in the Piedmont region and in the eastern part of the Pennine Alps mountainous sector, recent climatic variations have characterized the winters and springs of the last 3-4 years in an 'anomalous way' compared to the past. The "large" rainfall "early" snowfall in November/December and the near-absence of precipitation in January and February, the "historically coldest period of winter", have resulted in the scarce presence of snow below an altitude of approximately 1500 m asl and have negatively influenced the formation of a seasonal snow pack. Avalanche events have also undergone changes, particularly in terms of the period of occurrence and type. In fact, in recent seasons, typically 'winter' avalanches involving the mobilization of dry snow have been exceeded in number and size by 'spring' avalanche events involving wet snow, which also occurred in typically winter months
