TC Errol was a weak late season system that briefly attained tropical cyclone intensity on 9 May before weakening early on 10 May, about 600 km north of Cocos Is. The system did not impact any island communities although eventually it did pass to the east of Cocos Is on 15 May as a weak tropical low. Operationally it was maintained at tropical cyclone intensity until 14 May, however reanalysis indicates that winds around the system were below gale force from early on 10 May.
