DeepMind's WeatherNext model achieves breakthrough forecasting cyclones

DeepMind's WeatherNext AI model has achieved a breakthrough in cyclone forecasting, providing an extra day of predictive accuracy compared to previous models—equivalent to a decade of meteorological progress. The model successfully predicted Hurricane Melissa's rapid intensification in 2025, enabling advance warnings that helped communities prepare. DeepMind is now open-sourcing the WeatherNext models to empower researchers and weather agencies worldwide in improving cyclone predictions and disaster preparedness.
