El Niño Watch Issued: High Likelihood of Development in 2026
• The Climate Prediction Center (CPC) has issued an El Niño Watch, indicating an 82% chance of El Niño conditions developing between May and July
• Current observations show ENSO-neutral conditions, with near-average sea surface temperatures in the east-central equatorial Pacific. However, subsurface temperatures have been significantly above average, and westerly wind anomalies have been observed. The North American Multi-Model Ensemble predicts El Niño to persist through the Northern Hemisphere winter of 2026-27, with a 96% likelihood. While confidence in El Niño's development is high, uncertainty remains regarding its peak strength and potential impacts.
Why It's Important?
El Niño events can significantly influence global weather patterns, including increased rainfall in some regions and drought in others. Potential impacts include disruptions to agriculture, water resources, and ecosystems. Communities in areas historically affected by El Niño should prepare for possible changes in weather conditions, such as heavier rainfall or prolonged dry spells.
