NOAA Says El Niño Could Become Strongest Since 1950
NOAA says the chance of a very strong El Niño is above 90%, with milder temperatures and wetter conditions likely across much of the country.
The Old Farmer's Almanac and NOAA issued seasonal guidance predicting a strong "Super El Niño" will warm the United States this winter, directing wetter, snowier conditions toward the West and South.
Forecasters expect Pacific Ocean temperatures to surge more than 2.5 degrees Celsius above normal, creating conditions the National Oceanic and Atmospheric Administration places at more than 90 percent probability for a very strong event.
Meteorologist Crystal Egger said strong El Niño winters "tend to favor a wetter storm track across the southern tier of the U.S.," potentially translating to above-average snowfall across the southern Rockies and higher elevations of the Southwest.
Climatologist Dan McEvoy cautioned that "the impacts aren't guaranteed to be super," noting past strong El Niño events produced mixed results from heavy flooding to drier-than-expected conditions.
NOAA will release its full Winter 2026–27 Outlook on November 19 as the Intermountain West manages drought conditions, with nearly 95 percent of the region currently experiencing impacts.
