DeepMind's AI Hurricane Model Gives Forecasters an Extra Day of Warning

In October 2025, DeepMind and Google Research's WeatherNext AI model predicted that a Caribbean storm would intensify into a Category 5 hurricane and hit Jamaica, doing so five days before landfall with 80 percent confidence. The storm, Hurricane Melissa, caused severe flooding and landslides, but the early warning gave communities more time to prepare.

A paper in Nature reports that WeatherNext predicts cyclones with unprecedented accuracy, offering forecasters about one extra day of lead time compared to existing models. Its three-day forecasts are as accurate as previous models' two-day forecasts.
