The 2026-2027 El Niño is expected to bring significant weather disruptions across the U.S. Northern and eastern states may experience prolonged heatwaves, while the southern U.S. could face drenching storms and potential flooding. The Southeast and southern Plains are at risk of snow, sleet, and freezing rain during the winter months. Florida may see an increase in thunderstorms, while other Gulf Coast areas could experience drier conditions. The West, already grappling with a severe drought, is unlikely to see substantial relief despite potential snowpack increases. The combination of El Niño and climate change could lead to more extreme weather events, including higher temperatures and stronger storms.
