Google DeepMind's WeatherNext AI model predicted Hurricane Melissa's path and intensity five days before landfall with 80 percent confidence, allowing earlier warnings to Jamaica. The model provides one additional day of lead time compared to conventional weather forecasting systems, making three-day predictions as accurate as two-day predictions from existing models. Earlier warnings enable communities to prepare better for cyclones and reduce casualties from flooding and landslides.
