The upcoming strong El Niño could significantly impact winter weather across the U.S. Southern states, including California, Texas, and the Carolinas, may experience increased rainfall, potentially leading to flooding in vulnerable areas. Meanwhile, the northern U.S., including states like North Dakota and New Hampshire, is likely to see warmer-than-average temperatures, which could reduce snowfall and affect winter sports and water resources. The Pacific Northwest and northern Rockies may face drier conditions, while regions like the Sierra Nevada and Colorado could see increased snowfall due to a southward-shifted storm track. These changes could disrupt winter tourism and agriculture, as well as increase the risk of extreme weather events.
