The World Meteorological Organization (WMO), representing the UN, warns that a developing El Niño is likely and could be strong in 2026, raising the risk of extreme weather events. Multiple outlets report that warm waters in the Pacific are driving El Niño development. The WMO’s message is that countries should prepare for changing weather patterns that may include higher global temperatures and greater heatwave risk. Several sources add that the same El Niño conditions can contribute to drought in some regions and heavy rainfall or flooding in others, depending on local climate impacts. One outlet citing a scientist says El Niño may intensify and affect seasonal conditions, including potentially hotter summers in the northern hemisphere, while also increasing variability that can lead to colder winters in some places. Another source notes the forecast period for development extending through the coming months, with guidance to prepare before the impacts fully emerge. Overall, the reporting is consistent that while the exact strength and impacts can vary by region, the UN and WMO urge governments and communities to plan for increased hazards, including heat and extreme precipitation.
