100-word summary
Google DeepMind's WeatherNext predicted Hurricane Melissa would hit Jamaica as a Category 5 storm five days before landfall with 80% confidence. Three days out, it jumped to near certainty. The storm became the strongest on record to strike Jamaica, and forecasters used the extra warning time to evacuate earlier than ever before. WeatherNext runs 50 "what-if" scenarios simultaneously, giving meteorologists a range of possible outcomes instead of a single forecast. The National Hurricane Center used it alongside traditional physics models all season and ranked it the most accurate for both storm path and intensity. The difference between three days' notice and five might not sound dramatic until you're moving hospitals.
