El Niño's effects will vary across the U.S. The southern states may experience increased rainfall and storm activity, while northern regions could see warmer and drier conditions (Yahoo News, 2026). The Gulf Coast and Southeast are likely to face heightened thunderstorm activity, potentially reducing wildfire risks. Conversely, the Pacific Northwest and Northern Rockies may experience milder winters with below-average snowfall, increasing spring wildfire risks. The Northeast could see milder winters with reduced snowfall but a higher risk of coastal storms, including nor'easters. Globally, El Niño is expected to exacerbate extreme weather events, including droughts, floods, and heatwaves, with significant economic and environmental consequences (WMO, 2026).
