A tropical low formed south of the Indonesian archipelago on 30 December 2006 and moved initially eastwards then took a general southerly track from 2 January 2007 weakening to the north of Port Hedland on near the Northwest coast on 3 January. On the 2nd the low was upgraded to cyclone intensity operationally and named ' Isobel ' but the post-analysis indicates that the low did not reach tropical cyclone intensity. The most significant impact was economic from loss of productivity caused by the disruption to mining and offshore drilling operations and by the temporary closure of the port at Port Hedland.
Tropical moisture associated with the tropical low interacted with a remarkably deep mid-latitude trough resulting in heavy rain across the Goldfields, Eucla and South East Coastal Districts. The heaviest rainfall was near Esperance .
