El Niño Expected to Bring Unprecedented Weather Impacts Across the U.S.
US · Published Sep 8, 2026
The National Oceanic and Atmospheric Administration (NOAA) has reported a greater than 90% chance of a very strong El Niño event this year, which could bring significant weather impacts across the United States. El Niño, the warm phase of the El Niño–Southern Oscillation (ENSO), is characterized by unusually warm sea-surface temperatures in the Pacific Ocean. This phenomenon is expected to strengthen through the end of 2026, with a 69% chance of becoming a 'historic event' surpassing previous El Niños since
California and the Southeastern U.S. are likely to experience intense storms and wetter conditions, while the Great Lakes region may see drier weather. The event could also lead to a warmer winter for much of the U.S., with potential for severe weather, flooding, and even record-breaking heat in some areas.

Impact & Risks

The impacts of this El Niño event are expected to be widespread, affecting millions of Americans. California and the Southeast are likely to face intense storms and increased rainfall, which could lead to flooding and mudslides. The Great Lakes region may experience drier conditions, while the South and Gulf states could see wetter weather. Warmer temperatures are anticipated across much of the U.S., potentially disrupting seasonal patterns and increasing the risk of extreme weather events. Historical data suggests that strong El Niño events have previously caused significant climate disruptions, including flooding and record-breaking heat.
