AUSTIN (KXAN) – New tools are making flash flood forecasting more accurate.
Last month, Google launched a new Flood Hub designed to help meteorologists and emergency managers better predict flash flood risk up to 24 hours in advance.

It’s one of several artificial intelligence tools now being developed to improve early warnings and reduce the dangers posed by fast‑moving floods.
Why flash floods remain difficult to predict
For years, flash floods have been a challenge to forecast because they can strike suddenly and far from riverbanks.
“Flash floods can occur anywhere. They are not confined to the river,” said Gila Loike with the Google Research team.
That challenge, Loike said, is what Google’s new system is trying to address.

Flood Hub allows the public and professionals to interact with a new AI model that shows where flash flooding is more likely during the next 24 hours. Unlike traditional river forecasting, the tool focuses on rapid flooding driven by intense rainfall.
Google said it trained the model using millions of real‑world flood reports, including two decades of local news coverage, to help fill gaps where sensor data does not exist.
Turning forecasts into real‑world impact
At the University of Texas at Austin, researchers are working on AI‑driven flood models that go beyond predicting rainfall totals.
“The community needs to know where the water may accumulate or may flood at the street or neighborhood,” said Wonhyun Lee, a flood modeler with the Bureau of Economic Geology at UT Austin.
Lee said his team is focused on determining what flooding could actually look like on roads. This includes how deep flood waters are and how long they may be…
