Hurricane Gabrielle outlook. ABC News(NEW YORK) — Hurricane Gabrielle, which has now rapidly intensified into a major Category 3 storm, is the second major hurricane of the 2025 Atlantic season, according to the National Hurricane Center. Gabrielle is also the second tropical system to undergo rapid intensification this year. On average, the second major hurricane forms around Sept. 19, meaning Gabrielle’s status aligns with what is typically expected during the Atlantic hurricane season. As the storm passes east of Bermuda, Gabrielle will produce large swells and rip currents along the island through early this week.
