El Niño Expected to Influence 2026 Atlantic Hurricane Season with Increased Wind Shear
The 2026 Atlantic hurricane season is anticipated to be influenced by El Niño conditions, which are expected to develop across the Pacific Ocean. El Niño typically leads to increased wind shear across the Atlantic, Caribbean, and Gulf regions, creating a more hostile environment for tropical cyclone formation. The National Hurricane Center has announced updates to its forecast products to improve communication of storm risks, including changes to the forecast cone and graphical tropical weather outlooks. Various institutions have released their hurricane season outlooks, with predictions ranging from below-average to above-average activity. The University of Arizona forecasts 20 named storms, nine hurricanes, and four major cyclones, despite the presence of El Niño.
