The frequency of natural hazards has been increasing in the last decades in Europe and
specifically in Mediterranean regions due to climate change. For example heavy precipitation
events can lead to disasters through the interaction with exposed and vulnerable people
and natural systems. It is therefore necessary a prevention planning to preserve human
health and to reduce economic losses. Prevention should mainly be carried out with more
adequate land management, also supported by the development of an appropriate risk prediction
tool based on weather forecasts. The main aim of this study is to investigate the relationship
between weather types (WTs) and the frequency of floods and landslides that have
caused damage to properties, personal injuries, or deaths in the Italian regions over recent
decades. In particular, a specific risk index (WT-FLARI) for each WT was developed at
national and regional scale. This study has identified a specific risk index associated with
each weather type, calibrated for each Italian region and applicable to both annual and seasonal
levels. The risk index represents the seasonal and annual vulnerability of each Italian
region and indicates that additional preventive actions are necessary for some regions. The
results of this study represent a good starting point towards the development of a tool to
support policy-makers, local authorities and health agencies in planning actions, mainly in
the medium to long term, aimed at the weather damage reduction that represents an important
issue of the World Meteorological Organization mission.
