El Niño 'Imminent,' Could Reshape Weather Patterns. Here’s What It Means For AL

TUSCALOOSA, AL — Meteorologists have a better idea of how a fast-developing El Niño could significantly reshape weather patterns in Alabama and across the Southeast this year.

The heightened risks vary widely by region, from heavy rain and flooding in parts of the Southwest and Southeast to drought and wildfire concerns in the Northwest, Northern Plains and Upper Midwest, according to a news release from AccuWeather, a private weather company.

AccuWeather expert meteorologists said the developing El Niño is unusual because it is expected to begin early and strengthen quickly.

“El Niño is not a storm," AccuWeather meteorologist Paul Pastelok said. "It doesn’t affect you directly overnight. But the stronger the signal, the more it can dominate other weather patterns and amplify extremes. This El Niño is developing unusually fast. Most El Niños begin in the fall. This one should start in June and strengthen quickly.”

El Niño is a natural climate pattern that occurs when sea surface temperatures in parts of the equatorial Pacific Ocean warm significantly above historical averages. That warming can trigger changes in global atmospheric patterns, shifting storm tracks and influencing rainfall, drought, wildfire risk and hurricane activity.

For residents in the Southeast and along the Gulf Coast, the biggest potential impacts are heavier rain patterns from late fall 2026 into early spring 2027.

AccuWeather said the pattern may help ease drought in the region, but it could also bring an elevated risk of excessive rainfall and severe weather.

Alabama may also face a heightened severe weather risk during the mid-to-late winter season, which is typically the state’s drier time of year.

Meteorologists say a stronger southern storm track could increase the likelihood of severe weather in Alabama and nearby areas.

Is ‘Super El Niño’ Still Possible?

AccuWeather indicates a potential “Super El Niño” if equatorial Pacific temperatures reach 3.6 degrees Fahrenheit (2.0 degrees Celsius) above average.

Pastelok estimates a 40% chance for this rare event, noting that current conditions must persist through late 2026 to reach that threshold.

Only seven such events have occurred since 1957, according to the Climate Prediction Center’s Relative Oceanic Niño Index. The last one was in 2015-16.

Hurricane Season Adjustments

El Niño typically increases wind shear in the Atlantic basin.

Wind shear, which is the change in wind speed and direction with height, can disrupt tropical storms and hurricanes before they organize or intensify.

AccuWeather’s 2026 Atlantic hurricane season forecast projects 11 to 16 named storms.

AccuWeather hurricane expert Alex DaSilva said the early arrival of El Niño is causing forecasters to lean closer to 11 named storms than 16.

“With El Niño’s arrival early in the hurricane season, we are now leaning closer to 11 named storms rather than 16 in the Atlantic this year,” DaSilva said.

Even so, AccuWeather warned that a quieter Atlantic season does not eliminate the danger, especially from storms that form close to the U.S. coastline. Those “homegrown” systems can leave residents with less time to prepare.

People along the coast and well inland should continue to monitor forecasts for tropical rainstorms, tropical storms and hurricanes.
