NOAA: El Niño >90% likely to reach very intense category in 2026–27 fall/winter

NOAA projects a more than 90% probability that El Niño will intensify to a very strong event during the 2026–27 boreal fall and winter, potentially rivaling historical records. The forecast implies elevated risks of extreme rainfall, drought, and temperature anomalies across multiple regions, with implications for agriculture, energy demand, and disaster preparedness. Uncertainty remains over the exact peak intensity and regional impacts, which will depend on evolving ocean-atmosphere coupling.
