In early October, Hurricane Isaias was crossing the Gulf of Mexico, and the forecast models disagreed about where it would come ashore. The traditional physics-based models leaned west, toward southeastern Louisiana or coastal Mississippi, with a slower storm. On October 9, Isaias made landfall near Destin, on the Florida Panhandle, as a Category 2 hurricane.

The clever bit

Google DeepMind’s model skips the physics equations that traditional models solve. It found patterns in thousands of past storms and the atmospheric data around them, then takes the current picture and projects the storm forward. Forecasters at the National Hurricane Center (NHC) never lean on a single model, so it sits alongside the physics models. The NHC started folding it into official forecasts last year, as part of a blend of the best performers.

From its first runs on Isaias, the DeepMind model pointed at the western Florida Panhandle. A preliminary verification by HurriLab, published by hurricane specialist Michael Lowry, found it was closest to the real landfall spot at Destin and timed landfall within a few hours, three days out. The physics-based European and American ensembles put landfall too far west and a full day or more too late. Over the 2025 season, the NHC’s own verification report found the DeepMind ensemble slightly beat its official Atlantic track forecasts from 12 to 72 hours.

Google DeepMind, in particular, has really proven itself the last few years as the gold standard model.

Hooray

A model that learned from old storms pointed at the right stretch of coast from day one, and hurricane forecasters now have it in the blend they use to warn people when to get ready and when to leave.

What comes next

NHC Director Michael Brennan’s team gives Google DeepMind regular feedback to improve the model. AI models can be updated in weeks or months, while traditional ones get updated once a year at best, and Lowry says the gains in a single year would have taken a decade or more. The NHC sticks with a consensus of the best models, because, as Brennan puts it, every storm has different forecast challenges.
