Flood is the flooding of an area where there is usually no water. It originates mainly from heavy and prolonged rainfall that can swell rivers to overflowing, bursting their banks and flooding the surrounding area. However, not all waterways occur and behave the same way. For example, torrents become natural rivers only when heavy rain falls. On the other hand, underground streams cannot be seen because they are artificially covered for long tracts. For these, as for sewer systems, the failure to contain excess rainwater can lead to floods.

In this section you can find the vigilance Bulletin and the Bulletin of national hydrogeological and hydraulic criticalities. They allow to check whether in your current location or in the place where you are directed there will be criticalities/warnings related to weather-hydrogeological and hydraulic phenomena. Through the Radar platform you can also view satellite and sensed data from the national radar network, rain gauge and thermometer stations, and lightning recording network.
