From Ben Noll's Twitter:
"The ECMWF+UKMET superblend* for December 2023-February 2024 is very active along the U.S. East Coast Consistent with an El Niño winter, above normal precipitation () is shown across the Deep South, Southeast, Florida, Mid-Atlantic, and Northeast as well as California. The risk for East Coast storms looks higher than normal, but cold air may be at a premium! The El Niño-fuelled jet stream is predicted to extend all the way across the Atlantic into Europe, driving frequent storm systems from the southwest. In Australia, New Zealand, southern Africa, parts of South America, and the off-equatorial Pacific, El Niño-influenced droughts are possible. *Superblend = combination of the ECMWF and UKMET seasonal forecasting systems, consisting of about 110 ensemble members. They comprise two of the best seasonal modelling systems."
