New maps have revealed where a strengthening El Niño, which forecasters say could become a rare 'Super El Niño,' may deliver unusually heavy snowfall this winter. Parts of southern Nevada, Arizona, New Mexico, Texas, Oklahoma, Arkansas, Louisiana, Mississippi, Alabama, Georgia, Virginia, the Carolinas and the Florida Panhandle are all expected to see several more inches of snow than they normally receive each year. The unusual outlook is tied to El Niño, a natural climate pattern that typically brings warmer, drier conditions to the northern US and wetter weather across the South. El Niño forms when the surface temperature of the Pacific Ocean becomes noticeably warmer than its historical average. A Super El Niño means those temperatures rise by more than 3.6 degrees Fahrenheit (2.0 degrees Celsius). In the US, the phenomenon pushes the natural jet stream, which flows over the center of the country, farther south, bringing moisture and storms to many southern states that rarely see snow during winter. AccuWeather meteorologists have predicted that this year's El Niño will likely be the strongest in recorded history, with sea-surface temperatures in the Pacific rising by 4.8°F (2.66°C).

Stronger El Niños mean even more intense winters in these areas, including snow totals that can rise two to ten inches above each state's yearly average. AccuWeather long-range meteorologist Paul Pastelok said in a statement: 'When you have a strong El Niño, it changes the weather pattern across much of the country. Those shifts can have a big impact on flooding, drought, tropical activity and even early-season snowfall.' During the Super El Niño, the National Oceanic and Atmospheric Administration (NOAA) has projected that the biggest increases in snow will be seen between January and March 2027.

Residents in central and southern Nevada, central and northern Arizona, portions of northern New Mexico and most of Virginia will be the likely recipients of much of this snow. However, Pastelok previously told the Daily Mail that the impact of this historically strong El Niño could end up affecting the weather for millions across the US into the following winter. 'This stuff takes time, and sometimes, even after the El Niño goes away by next year, the lag of the atmosphere continues to go on, so we could see effects from this El Niño all the way through 2027,' he explained. The 2026-2027 El Niño has already surpassed the 2023 'marine heat wave' in the Pacific, with water temperatures rising over 3.8°F (2.1°C) above long-term averages in July.

Forecasters now believe the Pacific will continue getting hotter during the second half of hurricane season from September through November. AccuWeather's prediction of an average increase of 4.8°F over those three months would make this El Niño one of the strongest since historical records started being kept in 1850. The current climate event is expected to surpass the extreme Pacific temperatures seen during the 1982-1983 El Niño (4.3°F) and the 1902-1903 El Niño (4.1°F). 'We are seeing a strong impact in both the Atlantic and Pacific basins, with extreme wind shear limiting Atlantic storm development, while the Pacific basin remains quite active, as we forecast back in the spring,' Pastelok added in a statement this month.

While major snowstorms may still be months away, the emergence of a Super El Niño has already sparked the formation of 12 named tropical storms and hurricanes in the Pacific this summer. The threat of more snow in the South would continue an ongoing pattern in many states which saw above-average snowfall over the last two winters. That includes major storms delivering several inches of snow in Texas, New Mexico, Oklahoma, Arkansas, Louisiana, Mississippi and Alabama - which were all affected by a historic January 2025 Gulf Coast blizzard.

Even the Farmers' Almanac, which has been predicting winter snow forecasts since 1818, has called for wet and cold conditions throughout the southern half of the US. However, the publication's forecast has predicted more rain and mixed precipitation in Nevada and Arizona this winter compared to NOAA's above-average snowfall prediction. From New Mexico to the Carolinas, Farmers' Almanac also forecasted that states along the Gulf would need to prepare for cooler weather, with increased chances of frequent storms all winter. 'When that colder air meets abundant moisture, some storms could produce sleet, freezing rain, or heavy, wet snow,' the almanac's annual winter outlook said.

Pastelok told the Daily Mail in June that these frequent storms could have a particularly devastating impact on an 800-mile stretch of the US from the South to the Mid-Atlantic, bringing torrential downpours, flooding, severe thunderstorms and tornadoes. 'As far as heavy rainfall and tornadoes, Houston to Atlanta, Orlando and parts of the Mid-Atlantic, pick a city... those are more concerning, especially as you get into later this year,' Pastelok warned. The Super El Niño is projected to mirror an infamous one from 1877, known for triggering severe droughts and crop failures around the world. That event contributed to one of history's deadliest famines, killing over 50 million people, mainly in India, China, Brazil and parts of Africa.
