What counts as a flood warnings
Flood warnings come from national or regional water authorities and civil protection agencies. They distinguish between river floods that build over hours or days, flash floods that follow heavy rain within minutes, and coastal storm surge. Watches and warnings name the affected river basins and districts, so the decisive information is always the local catchment, not the country average.
