Hurricane Gabrielle (2025)

Hurricane Gabrielle, known as Storm Gabrielle while extratropical, was a powerful tropical cyclone that threatened Bermuda, and later affected the Azores as a post-tropical cyclone in September 2025. The seventh named storm, second hurricane, and second major hurricane of the 2025 Atlantic hurricane season, Gabrielle formed from a long-tracked tropical wave in the central Atlantic on 17 September. Due to dry air and wind shear that had stifled its development, the system was initially disorganized with an ill-defined center. These same factors prevented further organization for multiple days following its formation. Gabrielle intensified into a hurricane on 21 September as conditions became much more favorable, before it rapidly intensified the following day, peaking as a Category 4 hurricane east of Bermuda. After maintaining for a day, increasingly hostile factors such as dry air and wind shear caused weakening to commence, weakening to a tropical storm just west of the Azores early on 25 September, becoming extratropical later that day as it passed over the island chain. The remnants of Gabrielle gradually spun down until moving ashore on the Iberian Peninsula on 28 September, dissipating later that day.

Although Gabrielle did not affect Bermuda directly, high swells produced by the hurricane still affected the islands as well as the East Coast of the United States. A hurricane warning was issued in advance of the storm in the Azores and multiple flights halted as a result, even though Gabrielle ultimately passed through as an extratropical cyclone. Gabrielle's remnants, after merging with another system, also went on to cause flooding on Mainland Europe.
