For the May average, low-level wind anomalies were westerly over the western equatorial Pacific Ocean, while upper-level wind anomalies were westerly over the eastern Pacific Ocean. Area-averaged subsurface temperatures anomalies remained positive, reflecting the continuation of widespread anomalous warmth below the surface of the equatorial Pacific Ocean. All of the latest weekly Niño indices were more than +0.5☌: Niño-3.4 was +0.8☌, Niño-3 was +1.1☌, and Niño1+2 was +2.3☌. In May, weak El Niño conditions emerged as above-average sea surface temperatures (SSTs) strengthened across the equatorial Pacific Ocean. and heavy rains and flooding in the Pacific Northwest and Canada, according to NOAA.Climate Prediction Center: ENSO Diagnostic Discussion HomeĮNSO Alert System Status: El Niño AdvisoryĮl Niño conditions are present and are expected to gradually strengthen into the Northern Hemisphere winter 2023-24. This pushes the jet stream to the north and leads to drought in the southern U.S. Gulf Coast states, this change in weather patterns results in wetter conditions and the area tends to see more flooding, according to NOAA.ĭuring La Niña, trade winds are stronger than normal and more warm water gets pushed toward Asia. The warmer waters move the Pacific jet stream, which is a current of air flowing from west to east around the globe, to the south, making northern areas of U.S. In an El Niño weather pattern, the trade winds weaken and warm water gets pushed to the east, toward the west coast of the Americas. Normal weather patterns blow the trade winds west along the equator. While the exact connection between climate change and El Niño is not yet known, El Niño does exacerbate the conditions that climate change is already causing on a regional basis, Schmidt said. It is "still unclear" how climate change impacts El Niño, Schmidt said. NOAA said there is an 84% chance of an El Niño with a greater than moderate strength and a 56% chance of a strong El Niño developing by the winter.Įl Niño may "give a boost" to global temperature averages in 2024, but it will probably not be enough to see more than 1.5 degrees Celsius increase in average global temperatures, Schmidt said. "El Niño tends to peak around December/January and it could be a minor event or a major one and the impacts that we'll see will depend on that," Schmidt told CNBC. The first advisory watch for El Niño was issued on April 13, according to NOAA. Schmidt, the director of NASA Goddard Institute for Space Studies, told CNBC. "We've been anticipating this for a few months and we are still waiting to see how big an event it will be," Gavin A. It also increases the chance of a warmer-than-average winter across the northern part of the U.S. In the United States, a moderate to strong El Niño in the fall and winter correlates with wetter-than-average conditions from southern California to the Gulf Coast, and drier-than-average conditions in the Pacific Northwest and Ohio Valley, NOAA said.
