Arizona could face a 'Super El Niño' in 2026. Scientists raise alarms
The U.S. National Oceanic and Atmospheric Administration’s Climate Prediction Center predicts an 82% chance of a strong El Niño forming by May-July 2026, with a 96% likelihood of it lasting through winter 2026-27, potentially becoming a 'Super El Niño' with severe impacts like flash flooding and altered weather patterns in Arizona. Models suggest Pacific Ocean warming could exceed 3 degrees Celsius, matching the intensity of historic events like 1982, 1997, and 2015, raising concerns about extreme storms and droughts in the region.
The U.S. National Oceanic and Atmospheric Administration’s Climate Prediction Center has warned of an 82% probability that an El Niño event will form between May and July 2026, with a 96% chance it will persist through the winter of 2026–27. Some climate models suggest this could become a 'Super El Niño,' similar to the extreme events of 1982, 1997, and 2015, which reshaped global weather patterns. El Niño occurs when Pacific Ocean surface temperatures rise above average, with strong events exceeding 1.5 degrees Celsius. A 'Super El Niño' involves warming of 3 degrees or more, triggering severe droughts, storms, and flooding worldwide. The European Centre for Medium-Range Weather Forecasts and NOAA projections indicate ocean temperatures could approach this threshold by late 2026, potentially making it the most intense since 1877-1878. For Arizona, a Super El Niño could bring wetter winters, stronger storms, and a higher risk of flash flooding, drastically altering the state’s typical desert climate. Climatologist Michael Crimmins from the University of Arizona noted that while El Niño events occur every two to seven years, their intensity varies, and this one could push temperatures 2 degrees above normal. The Climate Prediction Center classifies El Niño events as weak, moderate, or strong based on temperature deviations. A strong event exceeds 1.5 degrees Celsius, while a Super El Niño surpasses 3 degrees, leading to unpredictable and extreme weather. Meteorologist Albert Martínez explained that these events disrupt global weather systems, causing severe anomalies. Arizona faces a critical turning point if this forecast holds, as the state may need to prepare for unprecedented weather shifts. The focus is no longer on whether El Niño will arrive but on its potential magnitude and the region’s readiness to respond. If the projections materialize, the impacts could be as severe as past Super El Niño events, demanding urgent climate adaptation strategies.
