While the low drifted slowly to the northeast, it began to lose its frontal system and acquire subtropical characteristics by October 7 . The next day, the storm encountered stronger wind shear, removing some of its convection, and slightly weakening the system; however, the storm eventually grew better organized and developed more convection around its low pressure center later in the day . Early on October 9, the system fully transitioned into a tropical cyclone, prompting the NHC to begin issuing advisories on Tropical Depression Seventeen . The tropical depression continued to strengthen, becoming Tropical Storm Ophelia later that day . Ophelia continued to strengthen due to low wind shear and on October 11, the National Hurricane Center upgraded it to a hurricane, making it the tenth consecutive storm this season to reach hurricane strength . Ophelia became a Category 2 hurricane on October 12 at 5: 00 p.m. AST (21: 00 UTC). On October 14 at 11: 00 a.m. AST (15: 00 UTC), Ophelia unexpectedly intensified to a Category 3 hurricane, making Ophelia the sixth major hurricane of the season and the easternmost storm of such strength in the Atlantic basin on record . On October 15, Ophelia began to weaken, while accelerating northeastward towards Ireland and Great Britain, with the storm's wind field also expanding . Early on October 16, Ophelia transitioned into a hurricane - strength extratropical cyclone, as it began impacting Ireland and Britain . </P> <P> In County Waterford, a woman was killed when a tree fell on her car, caused by the winds from Ophelia's remnants . In County Tipperary, a man was killed while clearing a fallen tree with a chainsaw . Another person was killed in Dundalk when a tree fell on his car . Two other men died after suffering fatal injuries while carrying out repairs to damage caused by Ophelia and Storm Brian . Hurricane Ophelia also fanned wildfires in Portugal and Spain, killing 49 people . </P>
