Hurricane forecasts apparently no better than a random guess
We have suspended issuing quantitative forecasts at this extended-range lead time, since they have not proved skillful over the last 20 years. We attribute the primary reasons for the lack of skill of our early December forecast due to the breakdown of several long-term relationships that worked well in many years of hindcast data, but not in real-time forecasting.
We would never have issued a seasonal hurricane forecast that did not show significant skill on many years of hindcast data. In addition, no statistical or dynamical models have shown skill at predicting El Niño – Southern Oscillation (ENSO) at this extended forecast lead time of 9-12 months. . . .
