The National Climate Center says equatorial central-to-eastern Pacific sea surface temperatures are rising and the event is expected to peak around November–December, forming an ultra-strong El Niño with a high probability of being the strongest on record. Since summer, China has shown typical El Niño impacts: eastern China has two north–south rain belts, heavy-rain episodes have been widespread and locally intense with overlapping affected areas causing compound disasters, and typhoon activity

The National Climate Center says equatorial central-to-eastern Pacific sea surface temperatures are rising and the event is expected to peak around November–December, forming an ultra-strong El Niño with a high probability of being the strongest on record. Since summer, China has shown typical El Niño impacts: eastern China has two north–south rain belts, heavy-rain episodes have been widespread and locally intense with overlapping affected areas causing compound disasters, and typhoon activity has been elevated with stronger storms and prolonged wind-and-rain impacts.
