Hurricane Helene (2006)
Helene turned into a "hybrid" storm with both tropical and extratropical features that afternoon, with a deep, warm core. After that, bigger shear weakened Helene once again, although it stayed as a hurricane-strength storm until it was fully extratropical on the morning of September 24. After becoming fully extratropical, the storm weakened as it moved eastward, becoming a gale center west of Ireland early on September 27. It eventually merged with a larger extratropical low near the northern end of the British Isles late on the 27th.
