Meteo-hydro risk. The alert system
Weather forecasts for civil protection purposes differs from the classic "weather forecasts". They highlight potentially harmful situations to people or things. Department and Regions elaborate forecasts daily summarized in the National weather watch bulletin.
Through the Radar platform it is also possible to view satellite and sensed data from the national radar network, rain gauge and thermometer stations, and lightning recording network.
On the basis of the forecast weather events, each Region and Autonomous Province assess critical hydraulic and hydrogeological situations (flooding, landslides, floods...) that could affect their territory. These assessments converge into the Bulletin of national hydrogeological and hydraulic criticalities daily produced by the Department. Consequently, Regions and Autonomous Provinces have to issue alerts for the local civil protection systems, while mayors have the responsibility to activate emergency plans, inform citizens about risk situations and decide the measures necessary to protect the population.
