Walls of ocean water, storm surges, which are forced onshore by storms, threaten the coast more and more. Sea-level rise caused by climate implies that current surges begin at a higher level (approximately 8 inches above 1900 and up to 1-8 feet above 2100) and floods are aggravated. Hurricanes have been very destructive in the U.S. with a damage of more than 1.5 trillion most of which is surge damage. Good predictions are essential: they will provide individuals with time to escape and government officials with time to act.
According to researches, current forecasts use physics-based models (such as NOAA's ADCIRC) that divide the coast into a grid. High-resolution runs can take many hours on supercomputers. Researchers now train machine-learning models on past storms and simulation outputs to serve as fast “surrogates”. These AI networks use storm data (wind, pressure) to predict surge levels quickly. Neural-net forecasts often match or exceed traditional models in accuracy. Scientists even train AI on synthetic hurricane data so it can handle rare or extreme scenarios. The result: surge predictions in minutes instead of hours.
The payoff is faster, life-saving warnings. AI-driven models could churn out flood maps at street-level detail in minutes, showing what will flood. Researchers are even teaching AI to assess hurricane damage from photos, filling data gaps. Already, AI tools are being integrated into operational forecasts to complement traditional models. As more data feed these systems, experts say coastal communities can expect even faster, more detailed storm warnings in the future — a crucial edge as climate change fuels stronger storms and higher seas.
