Where to check first, not what flooded

In the 0 districts that meet the evidence bar, the corridor drawn from the first report beats an equal-area circle, and each figure is shown with its band. It is a first place to look, not a map of the flood: in most districts it holds only a minority of the localities that go on to report.

The first report: The corridor is the best guess of where water goes next — send the first check along it.
A second locality within 5 km: The corridor is withdrawn. The reports now outline the flood better than the terrain does, and by eight a circle on them beats this layer.
Corridor unavailable: Not evaluated yet, below the evidence bar, or the locality failed the geometry checks. Flood reports stay on the map; an unavailable corridor does not indicate lower flood risk.
Assumed depth: JPS depth readings are unusable (6,780 exact zeros), so depth is an assumption you choose.
