Overview
- NOAA has officially issued an El Niño advisory confirming El Niño conditions are present in the tropical Pacific and says there is a high chance the event will strengthen rapidly.
- NOAA assigns about a 63% probability that the event will reach the 'very strong' threshold between November and January and ensemble models from ECMWF and others show unusually consistent signals that a record‑level event is plausible.
- Forecasters and the WMO say the strengthening El Niño is likely to raise global mean temperatures and tilt seasonal weather patterns, increasing odds of heatwaves, droughts, heavy rains and shifted storm tracks in many regions.
- Regional authorities are already responding: India’s IMD forecasts below‑normal July rain and officials are preparing contingency plans while UN and humanitarian agencies press for pre‑emptive funding.
- Key uncertainties remain because other ocean patterns such as the North Atlantic cold anomaly and the Indian Ocean Dipole can change regional outcomes, so seasonal forecasts will be updated as ocean and atmospheric signals evolve.
