24hflash-flood alerts, global
Google's urban flash-flood model now gives up to 24 hours' notice worldwide; whether anyone acted on an alert hasn't been measured.
Launched March 2026, the model is trained on news-derived ground truth, with precision and recall in South America and Southeast Asia comparable to rich countries; Flood Hub covers 150+ countries.
What would change this
An independent impact evaluation (evacuations, losses) tied to specific alerts.
