How strong could a hurricane get today — and over the next two weeks?
Potential intensity is the thermodynamic speed limit for a tropical cyclone: the strongest sustained wind the ocean and atmosphere can support. climatlas computes it every day from ERA5 and the ECMWF IFS analysis, runs it 15 days ahead on the IFS forecast, and sets it against 47 years of record.
