The area colours are the ones the agencies’ own services draw with, sampled from the images that come back. Station circles are coloured ONLY where the source publishes thresholds: where it does not, the circle stays hollow, because on a flood page an invented colour would say “careful” or “all fine” with nothing behind it. Mind how far each dataset reaches: municipal boundaries and imagery cover the whole of Italy; flood-prone areas and hydraulic works stop at the Po river district; the stations are those of the open-licence public networks we have been able to integrate, listed under the sources. Outside those perimeters a layer is not empty because there is no risk: it is empty because there is no data.

River levels
Sorted by how much they moved in the last two hours, rising ones first. The value is in metres above the section’s own gauge zero, which differs from station to station: compare a station with itself over time, not with another one. Two warnings that come from the data rather than from caution: the change is computed on medians of three readings, because single readings occasionally jump half a metre and that is a sensor fault, not a flood; and on a quiet day the list is dominated by estuary and delta stations, which move with the tide.
