DeepMind's WeatherNext AI gives forecasters an extra day to predict cyclones
DeepMind's WeatherNext model achieves breakthrough forecasting cyclones
In a Nature paper, Google DeepMind and Google Research, with the National Hurricane Center and UK Met Office, show their WeatherNext model predicts cyclone track, intensity, and wind structure with state-of-the-art accuracy, gaining over 24 hours of lead time—roughly a decade of meteorological progress. The model, now open-sourced, helped forecast Hurricane Melissa's 2025 landfall and runs 1,000-member ensembles in under a minute on a TPU.
On average, our model gives forecasters an extra day’s worth of predictive accuracy: our three-day forecasts are as good as what prior models were able to provide for only the next two days.
