Strong El Niño to Reshape U.S. Winter Weather Patterns
US · Published Sep 9, 2026
A strong El Niño event is developing, with a 90% chance of reaching historic intensity during the 2026-27 winter season.
This climate pattern is expected to bring wetter conditions to the southern United States, while the northern Plains and Rockies may experience warmer and drier weather.

Impact & Risks

The changing weather patterns could significantly affect U.S. agriculture, particularly in regions like the southern Plains, Southwest, Rockies, and northern Plains. Increased winter precipitation may improve soil moisture and water supplies for the 2027 growing season, while drier conditions in the northern regions could lead to challenges for rangeland and crop production. Warmer temperatures may also reduce snowfall at lower elevations, impacting water resources.
