Short summary
This study examines the seasonal and synoptic forcing patterns linked to debris flows occurring in the eastern Italian Alps. Results highlight that seasonal and synoptic pattern dependence is pronounced in both the debris-flow occurrence and the properties of triggering rainfall. Therefore, considering classification of debris flow events according to season and atmospheric circulation patterns can be used to improve existing warning systems that are operating on the basis of rainfall thresholds
