Atlantic hurricane update: How El Niño could reshape the rest of the season
A strengthening El Niño is likely to shape the 2026 Atlantic hurricane season, potentially dampening activity later in the year while posing risk closer to land early on. Forecasters anticipate a moderately active season with notable storm development near the Gulf Coast and the Carolinas, driven by unusually warm coastal waters and atmospheric wind shear. The season’s progression hinges on El Niño's evolution, Atlantic Niña conditions, and the Main Development Region’s recent stability, which could constrain overall activity. Landfall threats persist, underscoring the need for vigilance as the peak approaches. Looking ahead, officials expect a quieter end to the season but not a harmless one, with ongoing monitoring of waves, temperatures, and regional impacts.
Dive Deeper:
AccuWeather’s forecast for the 2026 season projects a mid-range level of activity, with a specified spread of named storms, hurricanes, and major hurricanes, reflecting a balance of potential development and suppression factors.
There is a 90% probability that El Niño strengthens to a super El Niño by season’s end, increasing upper-atmosphere wind shear that tends to reduce tropical cyclone development in the latter part of the year.
Tropical Storm Arthur caused record rainfall in parts of the Deep South, including an extreme rainfall event in Cottonport, Louisiana, highlighting the season’s potential for disruptive flooding near land.
Tropical Storm Bertha tracked close to the coast before landfalls in Louisiana and near the Louisiana–Texas border, illustrating how storms can form and intensify near inhabited shorelines.
Scientists are watching Atlantic Niña conditions, which would imply cooler eastern Atlantic waters and a potential decrease in storms in that region, adding complexity to the overall activity pattern.
Attention remains on the Main Development Region, where persistently stable conditions over the past two years have hindered thunderstorm formation and may further limit regional storm genesis this season.
