Atlantic Season Reaches New Record Without a Hurricane

Scientists say a powerful El Niño has strengthened upper‑level winds over the tropical Atlantic, cutting off storm growth.

Overview

  • The basin has produced no hurricanes through mid‑September, with the Sept. 12 mark setting the latest first hurricane in the satellite era.
  • Researchers link the lull mainly to record‑strong vertical wind shear driven by El Niño, which rips apart nascent storms by changing wind speed and direction with height.
  • Saharan dust, dry mid‑level air and fewer convective seeds have combined with the wind shear to suppress development; accumulated cyclone energy is at a post‑1950 low and only five short‑lived tropical storms have formed so far.
  • The same El Niño has boosted activity in the eastern and central Pacific, producing many more named storms and impacts as far west as Hawaii.
  • Forecasters urge caution because the National Hurricane Center sees no development in the next week but late‑season Gulf or near‑U.S. storms remain possible and some private models still project a modest uptick later this season.
