A historic Super El Niño is expected to peak during late fall and winter 2026–2027, with NOAA estimating a 75% chance of record-breaking strength since
This phenomenon, characterized by unusually warm Pacific Ocean waters, is anticipated to significantly alter the jet stream, shifting storm tracks and temperature patterns across the United States. The Pacific Northwest and northern Plains are likely to experience warmer, drier conditions, while the South and Southwest may see increased storms, heavy rain, and potential wintry weather. The Great Lakes and Ohio Valley regions could also trend warmer and drier, though lake-effect snow remains possible. NOAA's forecast highlights above-normal temperatures for much of the northern US and wetter conditions in the southern regions, emphasizing the variability and unpredictability of individual storm events.

Impact & Risks

The Super El Niño's impacts will vary across the US. Warmer and drier conditions in the northern regions could reduce low-elevation snowfall, potentially affecting water resources and winter recreation. However, major snowstorms remain possible during brief cold snaps. In the South, increased storm activity raises the risk of heavy rain, flooding, and occasional wintry weather, which could disrupt travel and infrastructure. The Northeast's weather remains less predictable, with potential for both mild and severe winter conditions. Residents in affected areas should prepare for a range of weather scenarios, including flooding, icy roads, and power outages.
