El Niño Winter Brings U.S. Flooding and Power Risks
The ongoing El Niño weather pattern is expected to significantly impact the United States this winter, with varying effects across regions. According to NOAA, El Niño typically shifts the Pacific jet stream, leading to wetter and cooler conditions in the southern U.S., while the northern states may experience milder and drier weather. California and the Southwest are likely to see increased rainfall and mountain snowfall, while the Gulf Coast and Southeast could face severe thunderstorms and tornadoes. These weather changes are attributed to warmer-than-average sea-surface temperatures in the Pacific Ocean, which alter atmospheric circulation and storm tracks. The 2026-2027 winter is predicted to be a strong El Niño season, with a high likelihood of extreme weather events, including heavy rain, flooding, and power outages.
