Abstract

Extreme weather events are getting massive media coverage as sign of climate change. Scientific research, for elaborating dynamic models in connection with anthropic activity, requires a closer flow of communication with citizens. In this contribution, the results of a research on the use of weather forecasting in Lombardy are discussed, collecting examples of bottom-up practices of communication and participation in hydrological risk. In particular, it emerges a widespread information overload of public weather bulletins that tends in the medium-long term to normalize the extraordinary event and atrophy the ability to mobilize resources to cope with the alarm itself.
