A new tool predicts flood clusters across many river sites for the next 1 to 10 years.
Adam Nayak, Pierre Gentine et al., Attention‐Based Stochastic Simulation of Climate‐Informed Spatiotemporal Flood Risk for Multisite Insurance Portfolios, Geophysical Research Letters.
A new computer model creates realistic flood forecasts for many river sites at once. It focuses on the 1 to 10 year time span that matters most for flood insurance contracts. The model learns from past weather patterns that match today's climate, then generates likely sequences of flood timing, size, and length. Tested on more than 100 sites in the Mississippi River Basin, it found that floods often hit many places at the same time, linked to known large climate patterns.

Tested only in one US river basin, not globally validated yet.
