The strengthening El Niño could lead to significant weather impacts across the United States. Central and Northern California may experience heavy rainfall, increasing the risk of flooding, while the Sierras could see substantial snowfall. The Gulf Coast, Southeast, and mid-Atlantic regions are expected to face wet and stormy conditions, including severe thunderstorms. Meanwhile, the northern tier of the U.S. may experience less snow and fewer cold air masses, which could impact winter sports and water resources. The Northeast and Midwest are likely to see milder-than-average winter temperatures, which could affect energy demand and agricultural cycles.
