According to Sundar Pichai, Google trained a new flood forecasting model to predict urban flash floods up to 24 hours in advance, and created Groundsource, an AI methodology using Gemini to identify over 2.6 million historical flash flood events across 150+ countries, which is now open sourced; urban flash flood forecasts are live in Flood Hub to support community safety. As reported by Google via Pichai’s announcement, the combination of Gemini based event extraction and a purpose built forecasting model addresses the data scarcity that has limited city scale flood nowcasting, enabling earlier warnings and operational planning. According to the announcement, enterprises and public agencies can leverage the open dataset for local calibration, model benchmarking, and integration into emergency dispatch, insurance risk models, and municipal resilience planning, while developers can operationalize alerts through Flood Hub outputs.
