## The human problem

Many communities lack the observations needed for reliable flood forecasts.

## The prior constraint

Sparse measurements limited forecasting in ungauged watersheds.

## AI’s actual role

A model learned from hydrological data across watersheds.

## The documented result

At up to five days ahead, reliability matched or exceeded same-day forecasts from the comparison system for extreme riverine events.

## Why it may matter

Earlier information could help communities prepare; the study did not measure lives saved.

## Limitations

Forecast skill varies by basin. Warnings still require local delivery, trust, and capacity to act.

## Unresolved questions

Evaluate forecast performance and warning access in more communities.
