DeepMind’s Hurricane Model Gives Forecasters an Extra Day of Warning

In October 2025, Google DeepMind’s WeatherNext AI model predicted that a Caribbean storm would intensify into a Category 5 hurricane and hit Jamaica, doing so with 80 percent confidence five days before landfall. Hurricane Melissa went on to cause severe flooding and landslides, but the early warning helped communities prepare.

According to a paper published in Nature, WeatherNext predicts cyclones with unprecedented accuracy, giving forecasters about an extra day of lead time on average. Three-day forecasts from the AI model are as accurate as previous models’ two-day forecasts, a difference that can be critical on the ground.
