How WeatherNext helped the National Hurricane Center better predict Hurricane Melissa’s historic landfall in Jamaica

WeatherNext, an AI weather model developed by Google DeepMind and Google Research, successfully predicted Hurricane Melissa's rapid intensification and Category 5 landfall in Jamaica five days in advance.

• •WeatherNext addresses the historical gap by accurately predicting both tropical cyclone track and intensity, whereas traditional models excelled at one or the other
• •The model trained on decades of global weather patterns and specialized extreme tropical cyclone datasets to overcome rapid intensification prediction challenges, where hurricane winds increase by 35+ mph in 24 hours
• •For Hurricane Melissa, WeatherNext predicted Category 5 strength landfall from a weak tropical depression with 80% confidence five days in advance, reaching near 100% three days before landfall
• •The National Hurricane Center provided unprecedented lead time to the Meteorological Service Jamaica, enabling early resource mobilization and effective evacuations
