The National Oceanic and Atmospheric Administration and other forecasters report that the current El Niño is likely to become exceptionally strong.
This atmospheric shift matters because it can disrupt global weather patterns, leading to severe droughts, floods, wildfires, and intense tropical cyclones. The phenomenon develops in the tropical Pacific Ocean and is projected to affect the Americas, Australia, Southeast Asia, Hong Kong, and southern China [1, 2].
Computer models currently show strong atmospheric coupling and unusually warm sea-surface temperatures [2, 3]. A NOAA spokesperson said there is an 81% chance [4] that the El Niño will strengthen by the fall of 2024 [4].
While some media reports use the term "super" El Niño, it is not an official meteorological classification [2, 5]. An ABC4 reporter said, "Super El Niño isn't a recognized classification, but the potential for a 'very strong' El Niño could bring super interesting weather" [5].
Historical comparisons vary among sources. NOAA said this could be one of the strongest events since record-keeping began in 1950 [6]. Other reports suggest it could be the most powerful event in 150 years [1].
The intensification of these waters often triggers a domino effect in global climates. For some regions, this means an increase in precipitation, while others face extreme dryness, creating a volatile environment for agriculture and infrastructure [2, 3].
“"We have an 81% chance that this year's El Niño will become stronger by the fall."”
The potential for a 'very strong' El Niño indicates a significant shift in global heat distribution. Because these events correlate with extreme weather, governments and agricultural sectors in the affected regions may face increased economic risks from crop failure and disaster recovery costs.
